I've never ridden a ktm, I had an old Kawasaki KX80 dirtbike growing up. My screen-name is my initials backwards.

Dug,

Sure, I'm 10 or so min away from your work near Worcester State U, I have some Pulp Daddy's and Soul Purpose beers from "the greater good" https://www.greatergoodimperials.com/# in the fridge, stop by and have a laugh at the project that I've gotten my self into.

I mean no offense to anyone, What is funny here is I did the maintenance he described and then some. In my 15+ years with the drives, I had the same set, replaced a trim ram and the hoses getting way too rusty to trust them but never had an issue with the drives themselves. On the other hand inside ...

I've removed a potentially offensive line.

I/Os and saltwater don't mix in my opinion.

No pics from Saturday's fun, I sanded down 3" on either side of where the bulkheads were going to go then glassed one side on the fishbox bulkheads with 2 layers of 6" wide 1708. I also glassed the fuel tank hatch frame together, I had a heck of a time getting it all aligned up and in the end one of...

maybe we can all agree on one thing, I/O = Inoperable or Intolerable

ktm_2000

The other thing, the b25 is about 8' wide at the transom, most cops don't give you a second look when they are behind you.

on the flip side at the helm it is near 10' and you can put a pretty good scare into a toll booth attendant if they stick their head out of the booth.

My boat is fairly light @5500# with full load of fuel... I have a venture dual axle 7500# capacity aluminum frame bunk trailer, I have kodiak 12" disk brakes on the front axle and surge coupler. I'm guessing my max load when fishing is @6500# so I'm 1000# over, also I went with the larger axles, the...

Dug,

I believe I've chatted with you before via email, are you the one who owns the machine / bearing business?

I live in Worcester.

ktm_2000

Carl, I agree with you that weight is further back on the race boats, but the other thing I notice is that both are driven from very close to the transom, I'm assuming the ride from the production boat helm location would not be friendly. The concept that is in my head is that Any bouncing up and do...

ktm_2000

to me the main issue is that a professional marine architect designed the hull around inboard power with weight in specific places. Unless great care is taken to evaluate where weight was and is going to, the hull might not provide the superior ride which we chose our boats for. In my Bertram 25 cas...

Cam, When putting the panels in, I was not going to do a fillet then glass over, I was just going to do 2 layers of 1708. On the hull sides, what did you use to sand? I don't want to break up the existing woven roving but would like a good surface to bond to. I was thinking of hitting the outside su...

today's activity #2 - Hatch for the oversized fishboxes I am creating. Years ago I traded board member CMP 2 of the cast bronze vents I wasn't using for his fuel tank hatches. When I removed the deck I saved the fuel tank hatch frame thinking that I could cut it down and reuse it with CMP's hatch. 1...

today's activity 1, making a new cabin floor panel When I cut the cabin down 22" I cut half way through the small hatch in the cabin floor. There were also cut outs where the original marine head hoses were installed. Years ago I removed the head and glassed in the through hulls which were under the...

Hi All, I'm rehabbing my Bertram 25 and have had a couple of threads on various topics and wanted to put them under one so there was only one thread to update. This spring and summer should see a lot of progress as a lot of the bits and pieces start to come together. I am converting my 1964 moppie t...

ktm_2000

btw, I am not saying that the boatworks guy's work is bad, whomever rehabed the boat prior to him.........

ktm_2000

I'm curious how this B31 rides in snotty conditions, without 2000# of metal sitting low in the hull fairly far forward, does the hull lift up then crash back down after going through a decent wave where a hull in the original config would go through them without a lot of bow lift? This is one of the...

ktm_2000

that guy is cleaning up a whole lot of messes. I'd rather work on a beat-up original boat than one that had been "renovated"

I hope my work is better than what I am seeing him re-doing.

ktm_2000

I started working on the cabin bulkheads and ran into a self created problem. Since I shortened the cabin, the opening for the cabin is smaller and the door opening does not match the floor space opening. I scribed the nida core panels to the hull sides and left myself @ 1/2" gap around the perimete...

ktm_2000

Congratulations!!!! I wish you many years of good times on board her.

ktm_2000

WaytooSlow, I'm coming over to your idea, slowly. I did a chat session with the Bob's folks and their impression is that with their 12" or 14" setback jackplate with its 6" lift will give me enough lift to not have to notch the transom and still be able to get the prop out of the water. They did not...

ktm_2000

I'm not sure how long the other folks who are re-doing their B25s have own/run their hulls prior to their projects but I wanted to share that I've owned my B25 for 15 years with I/Os and love the way that the boat rides but just couldn't handle constantly fixing the motors. My experience with the hu...

ktm_2000

The fuel tank hatch on different B25 models was either 1 piece for the 4 cyl models and 2 piece for the 6 cyl models. from your pic, it looks like you have only 1/2 of the 2 piece model fuel tank hatch opened. you should be able to take the other 1/2 up and get at the fuel tank. In my case I had str...

ktm_2000

I watched the video they through bolted the cleats and the nuts are on the outside of the boat

Is there a way to avoid this

ktm_2000

I'm a heathen for carving up my B25, but I/Os are just too much to deal with. I don't know that I could do that to a 31 In the pics there is one of the transom and looks like a raised pad was added to bolt the cleats to the hull, I am interested in how to do this cleanly. How would one do this, put ...

I grew up with and am still good friends with a set of twin Greek guys. Their usual pairing of Ouzo is with other alcohol types, so no knowledge of what it should be had with. They only drink Ouzo straight and both of them have a hole in the bottom of their leg so when the bottle of Ouzo comes out I...

ktm_2000

Andre, In my boat I am planning on re-using a portion of the fuel tank hatch, the concept is to cut around the hatch leaving an excess of 4" around the perimeter then taking the core out of that 4" of excess. From there I will fit the hatch into the new deck and grind down the core where the excess ...

ktm_2000

Yannis, you seem like you are a true aficionado of Ouzo

Bruce, some funds are on there way via paypal.

resurrecting this thread as Springtime allows me to start work again. I can't wait till it gets a bit warmer, still too cold for glassing so I am trying to get any work done that I can. I templated and made up the front bulkhead out of nida-core which has a layer of 1708 on both sides then measured ...

I mostly stand-up fish so I'm more wishing than wondering. I do have a set of bent butt 80s so I think I'm good below 35#

on the 0 degree transom rod holders, are the lees swivel ones good enough for a giant or does one need to get a more heavy duty rod holder?

damn maritime sky rats!!! different species different issues, all sky rats. A while back I had a lobster boat on a mooring and the seagulls would drop crabs and quahogs on the deck to break them open, after their snack would go up and take a nap sitting on my radar taking their dumps on my hard top....

Last weekend I chopped off 8" more of the old motor box. I messed up the cut somewhat in that the sides are scribed to the transom angle but the top portion was not. I will have to cut 1" more off so I can scribe it to the transom. In the end it will stick out 12" beyond the transom cap and the back...

I left the joint which Cam describes intact. My plan is to raise the height of the main stringers to match the height of the lip, then place my new deck panels on top.

Cam, Looking good, did you through bolt the helm to the deck? when you planned it out, did you put extra blocking under the deck to distribute the loads? On the tabs, my boat with twin I/Os had them originally and I took them off as I never used them, pump was dead when I bought the boat. I still ha...

Cam, I have an area of my basement filling up with boat parts which has a corresponding suction sound of $$$ flowing out of the wallet.

Hi All, Most of you all have twins and with that some redundancy on the water, I'm headed down the path of a single motor and am interested in what items I can design into the boat to minimize fuel and electricity issues.

Pete, I get your point. One of my buddies has been tearing apart my idea based upon access to the bilge and has suggested exactly what you have. as designed, the front of the motor well would be 27" off the front face of the transom, any hatch most likely has a 2" wide flange. My design runs into a ...

Steve, Thank you for the collection of B25 outboard pics. I am quite interested in how each of the boats solved the issues of less weight. There's a lot of wisdom in Willard's statement about messing with weight as in each of the images the rear chines are out of the water on all of the boats. The o...

looks good, welding is much faster than glass work.

one question why not have the 2 front bolts fully surrounded by steel?

ktm_2000

I spent some time today messing with the old engine cover and unless Cam come back and says I could use a jackplate without notching the transom I think I will go with the idea I opened up this thread with. My boat was setup with 3.0Ls and the short engine box so I measured the box and it is 25.5" f...

ktm_2000

Yannis - I fully understand your point, I will not be storing the boat in the water and my thought process would be completely different if I were storing in the water. I fish the area around cape cod, Trailering gets me a huge radius of fishing grounds and minimizes running time on the water. Our h...

ktm_2000

Cam, I'm still curious, when you jack up your jackplate to it's max height and then tilt the engine forward to the line of the original transom could you get the prop out of the water? If the answer to that question is yes, or even pretty darn close I'd go with a 14" setback jackplate in a heartbeat...

ktm_2000

I'm pretty sure I do not want a bracket even though I would love a closed transom. My parking space for the boat is not too far off the road, when I parked the boat when it had I/Os my truck was in part of the street, If I put the motor 4+ feet further back I would block more of the road. I haven't ...

When does it get warm enough for boating down your way? I'll bet you can't wait.

the end is near, can't wait to see this rig on the water.

Hi Folks, While it is cold and resin won't cure well, I am trying to plan out my project. As of now I am planning on a 300hp suzuki 30" shaft outboard for power and the outboard being installed directly on the transom. I would love a full transom but don't want to mess with a bracket.

Matt, I googled the alignment tool and one came up on ebay for $20, much less expensive than the $100 + one I bought years ago. To allow your project to move forward faster you might want to pick one up, get the engine mount base close to right then after the engine is installed bring the boat to yo...
