I have the ZF45's in mine. They run the same ratio forward and reverse. Actually there is no forward or reverse per say. Just depends on how you hook up the shifter cable for the propeller rotation. You only need to carry one spare prop if you are into that kind of thing. 8 degree down angle on them...

With all this talk of swallowing and getting banned for life I was expecting that link to contain porn.
So disappointed.

Kevin

I spent a few(at least 5) minutes looking at it also just wondering. We usually just state problems or ask for advice. I am not going to lie, deviating from the norm is a lot of fun! Trying to get into the head of a fellow boat owner as to what something is and why it was done. My final guess is onb...

Kevin

A mistake!

Kevin

Who would bother fixing up a B28? It's like polishing a turd. My humor is off key today! I think that was a bit more work than the average minion like myself could do. Looks way better than mine but I would be afraid of using that cabin. There would be yellow caution tape keeping people out of it if...

Kevin

Gert,
That is really nice. I actually like the look of the boat without a hard top/bimini etc. Reminds me of the factory photos of our old boats. Timeless lines with a touch of Gert.

Kevin

Yannis,
I never addressed it due to time constraints. When the weather cools and time allows I am going to cut a portion of it out so the pump and switch can do a better job of getting the water out. I will post a photo after the job gets done. It might be a while though.

Kevin

Dry weight spec from factory with small blocks is 12,060.
Add fuel, water and gingerbread call it 14,000 to be safe.

Kevin

Looks great Jimmy. I like those ramps for the engine mounts. You can reach nuts and bolts that fall under the engines!

Kevin

Yannis, I pulled my deck in 2005 when I purchased my 28. I just bought a tube of 4000 a few weeks ago but have not sealed it yet. So, I have been using the boat with the cockpit held in place by gravity only for many years. The only issue is what Bob mentioned. You may get some dripping on the back ...

Kevin

I have never had a generator on my boat so I assume it has its own alternator for charging its battery while running. Maybe the generator powers the onboard battery charger? At any rate, I would suspect any good multiple battery system should incorporate Automatic Charging Relays (ACR). The alternat...

Kevin

My sleeper. Not as pretty, but healthy.

Kevin

Projects are fun! So you going to be able to drive that car down here or what? They do a car show in December every year @ the local HD. Nothing serious, so I will probably put my ride in it this year. 50' free dive is impressive in my book. I go all the time but usually 20 footers or so. I did a 45...

Kevin

Picked them up today, installed and sea trialed. Ended up with 17x14PP. I guess the leading 1/3 of the blade is 13P, the middle is 14P and the trailing edge is 15P. That is how it was explained to me. The cup is now only on the outer 1/3 of the trailing edge as opposed to starting at the hub. WOT wa...

Kevin

Bill, the trip was good. We covered the whole Berry Loop but did not actually see much of what I intended on seeing. 6 people, one of which was a 2 year old created some challenges that were a bit to overcome. The guys wanted to rough it (camp) but weather did not cooperate. We were always safe and ...

Kevin

Dropped off the props and had a discussion with the man that has been working on my props since 2005ish. I told him where I was with the new props and where I wanted to be. I told him that I wanted bow lift. He knows me and what I am after. He said we would have to add rake but that he could not do ...

Kevin

I am pretty sure it has 6V92's. I read it I somewhere. Sorry, could not resist!

Kevin

That boat looks nice! Can't wait to see what you do to it.

Kevin

"The enemy of good is better" I saw that coming! Slip with my bronze 17x15 props equals 13% using the calculator. 15 pitch, 1.5 gear reduction, 4000RPM 33MPH Slip with Nibral is 17x16 props equals 9%. 16 pitch, 1.5 gear, 3800 RPM 35MPH Since my last post my new to me props arrived. Tested them out a...

Kevin

Bob, What would you do in my case? Current set up is 17x15 bronze with medium cup. Boat runs great at cruise of 25 knots and reaches WOT spec @ 29 knots. Would 17x14 with heavy cup be better? I don't care about top speed, just the cruise speed and being able to hit WOT spec on the engines. Carl, Add...

Kevin

Bob, I don't see the connection between tabs and rake. Tabs can help level the boat or push the bow down....lift the stern maybe? You say that positive prop rake helps lift the bow right? Have you known anyone that experimented with adding rake to the props on a 28 hyena? I am sure the 28 and 31 are...

Kevin

Corey, Welcome to the club house. The guys have given lots of really good advise. One thing that strikes me as vey true is get something you can use from day one. Fix things and make improvements as you go. My boat had some issues with the iron and my mechanic skills fell short. I spent the first ye...

Kevin

Yeah, my mind does not grasp how cupping the leading edge of the blade would or could work. I would think that would cause a lot of boiling water. I have tried a lot of things that were debatable for performance on cars and boats. The rake I understand.... I think. But why would our props not come w...

Kevin

Did you try the 8 ounces of water and one ounce of dawn dish soap trick? Put it in a spray bottle and shoot it through turbo while at cruise speed/load.
Chasing a ghost is no fun.

Kevin

Bob,
So how do we do it?
I have a pair of nibrals that should be here this week. I plan on throwing them on and seeing how they compare to my current bronze set up. The nibral have an extra inch of pitch so my comparison won't be apples to apples.

Kevin

Bob,
How does the trap line affect the fuel pump on the engine? Is it an over loading issue? I am not familiar with those engines or pumps.

Kevin

What Carl said...... He is the voice of reason! I was thinking that I would have to pull a motor and put new seals in a transmission due to red stuff all over the bilge. I was upset and not thinking clearly. Luckily, the faithful go me straightened out and the problem was a .50 cent washer and 5 min...

Kevin

Did the boat sit in the water for at least a day or two and have a final alignment done prior to sea trial?

Kevin

Good looking boats guys, congrats. What are the performance numbers as far as cruise speed and fuel burn on those 35's? My wife commented about getting a larger boat. I think a larger boat would be nice in some regards but the boat we have is treating us very good.

Kevin

I am looking for a pair of Michigan Nibral DJX 3 blades 17x15 with medium cup. My shafts are 1 1/8. I will likely have to get 1 1/4 bore wheels and use bore reducers due to lack of availability of 1 1/8. I have spoken with every prop place around and extensively searched the web. Do any of the faith...

Kevin

Thanks for the offer Bill. We are pulling out of here Monday morning for the Berry loop. Have you heard from or seen John up there? We spoke in may and he was heading to Chub with his boat. He was not sure if he was going to leave it there or bring it back and then do the crossing with us again. I h...

Kevin

Thanks for the resources fellas. I made a gross miscalculation and assumed these lines were something I could do real quick locally. I expect to be knocking out about 500-600 NM this next week, hopefully I don't need to rely on my back-up plan. When I get back I will order some new ones and keep the...

Kevin

Gents, I tried to get some replacement oil cooler lines from transmission to oil cooler. NAPA nor the diesel stores sell these fittings which are inverted flares or so I am told. Can anyone advise what the operating pressure of the fluid is in these lines while transmission is operating at cruise to...

Kevin

Jimmy, My lines look like plastic/nylon tube very similar to the tube used on my trim tab system. The steering tubing is just larger. I do not know the proper terminology for the brass connectors, but it is a nut and ring that slides onto the line itself locking it on as you turn the nut. Compressio...

Kevin

A lot of black smoke would be a sign of not enough air, right. Or is it too much fuel? The whining you hear makes me think boost is escaping at higher pressures. I would expect loss of boost to radically decrease the power output/RPM. Could your filter be collapsing or clogged? Just a thought.

Kevin

That's the mean guy we were looking for.
Did you shoot that particular one with .50 BMG?

Kevin

I call BS. Pretty sure she said you stab the shark, inject it and then it floats to the top. I bet you 500 bucks you can't get a good enough swipe at shark or bear while it is trying to eat you.
You could simultaneously flatten a tire and fill it up though. Just sayin'

Kevin

Paul, I am leaning towards fuel/carb since you said it lost RPM's then revved a bit before it stalled. Only one engine having problem right? If so that should eliminate the likely hood of clogged tank vent. I would suspect carburetor. Checking grounds are pretty easy so it can't hurt. If you don't f...

Sure....blame the beer belly!

Kevin

Yannis, I tried a homemade puller and failed. It was suggested to me that I just unbolt the struts. Of course the props have to come off but then you just slide the struts off the end of the shaft. Then a hack saw can be used to remove the bearing. There should be a couple posts here in the past yea...

Kevin

I has been a very arduous past few months but I have made lots of progress on the boat. The bow railing is gone. Looks much better. Never go up there anyways and the railing was nothing more than an ankle biter. Tinted the windows. I used to do that for work in my younger years and you lose your tou...

Kevin

Pete, The bolt at 1 oclock in relation to the dummy plate(gray painted part by hex wrench) was the one I thought it was. I put a new crush washer in. Filled with fluid, tweaked alignment again since coupler was apart and put it all back together again. Fired up the motor and inspected. Immediate lea...

Kevin

Bill, I think you nailed it! The right side of the bolt you can see the washer disintegrated when I touched it. Of course the ball bearing and spring came out with it......hope they go back in easy. This is the bolt on the right below the neutral safety switch. I should probably do the one on the le...

Kevin

Yeah, some rust. I will clean it up and put it back together with some CX Heavy. What about some of those bolts or hex bolts on the back of the housing, could they leak? Guess I will have to clean it up good and run it for a bit to better isolate it. Never ends. I did get engine data to the MFD. Ver...

Kevin

Thanks Bruce. I just broke them apart. They seem to be dry as a bone on the inside.

This is where you are talking about right?

Kevin

I had removed the hydraulic lines while doing maintenance a month or so ago so to clean the coolers. I topped of the fluid accordingly when I was done. I did lots of other work like alignments since I had installed new mounts. There was the slightest bit of ATF on the back of the case at the bottom ...

Kevin

Did anyone pony up yet to build the 31 that will do 80 knots?

Kevin

Pete,
I am not having any problems with the anchor locker. Maybe my sniffer is not working?
Doesn't fresh water rot things though where as salt water does not, or at least less?

Kevin

Frank, You are correct that the officer is responsible. There is really no way around that. If a ski type vest is worn, the only way to get it on properly is the vest goes on first, then the cuffs. That is assuming you have a compliant subject. Most of the time it is the horse collar type PFD that i...
