4623115-6083144 are the common engine serial numbers for a 454, 330 model in the year range 77 to 81.

Bruce

Mike,
What is the rpm/hp curve these engines were built for?

Bruce

When I was a wee lad of questionable character in the boat biz up north for two winters we always made sure our storage boats had charged up batteries before putting up and disconnecting cables. Very rare did we see an issue. We stored over 100 boats. Cold weather kills low and weak batteries. Of co...

On a non recovery system the level can be a couple inches down to allow for expansion when hot.
Tony is right. Install a recovery tank with the proper pressure cap.

Bruce

Joseph,
The only other paragon setup I saw in a 25 was a paragon gear with a walther vdrive.
You must have a real early model, whats the year.

Bruce

Front half is a Borg Warner, v-drive looks to be a thermo electron, aka crusader.

The US 25 v-drives used BW/Walters.

Bruce

The folks at A&J are good people.

Bruce

Welcome Pat.

Nice to see someone with over 5k on the hour meters.

Bruce

Peter, You can start by sitting down and figuring out both on ac and dc what circuits you will need, Example ac, outlets, air con, reefer, gen set or just shore. DC, running lites, engine ignition, horn, bilge pumps, ect. Write it down on paper, mull it over a few times and this will decide the size...

They are in Fairhope where Harry Babb is, you might pm him to get some local knowledge but they have been mentioned in other posts as being a good company.

Bruce

I used one on a repower in 07 in a trawler. It ran good, always had good service with perkins. Parts sometimes were an issue.

Not sure if those were what Brewster had in his boat before the 6lp repower and sold them to Russ P for his 31.

Bruce

Yes, thanks Mike.

Your a true class act.

Bruce

Tony,
We are good to go till next year.

Bruce

Gotta thank everyone, including the new guys for keeping this place going.

It's been a year since I settled Pats estate with his sisters and Pat would be very happy.

You guys are the best!

Bruce

Prayers go with you Pete. Let me know if you come down.
Come over to the shop and see all the car projects going on.

Bruce

Don't normally promote businesses too much but http://www.chapmanmarine.com in Stuart just helped me out getting some wiper motors. Very friendly, went out of their way to help and just about matched my deep discounted net price I found on line that would have taken weeks to get I got in a few days ...

Engine will always be the higher rpm vs shaft using a reduction gear.

Bruce

Welcome from a back yard neighbor in Gardens and Jupiter.
There have been a few outboard 31's done nice like Triple C in Port Aransas Tx.

Bruce

Tony, Funny and you have no idea. 8) My dad was an engineer for Philco then Ford and ran their advanced development lab. Member of SAE, IEEE, had 92 patents, 27 technical papers. Here's one of his more well known co patents. http://www.google.com.na/patents/US2769855 Actually what Marlin is doing is...

Bruce

Scott, If I remember correctly that engine is rev limited at 5150. So 4900 to 5000 would be WOT. At 4900 it would not be 60% throttle unless you were way under propped and just ran out of cable throw on the controls only opening 60%. Have you checked at wot at the cable/engine throttle connection to...

Bruce

Tony is correct. With 2:1 on those 496, that was a lot on 1 3/8. But you got 7 years, not bad. 2:1 is correct for current setup due to rpm I saw the same setup on many new boats all the time when 7.4l went away and big boy gas came along, then a few years down the road 1 1/2 shafts became more stand...

Bruce

As a former Yanmar dealer, among others, would I buy a yanmar in the US today? No. Mores because I think Yanmar America eats it. But I will tell you numerous engines I installed and serviced had over 10,000 hours without any major service as did other brands. Two pairs of 3208's in dive boats had ov...

Bruce

Terminal strips are usually the junction between the breaker and the load.
It aids in allowing the builder to pre wire a panel with a pigtail built in a shop, then install on the boat and connect to loads that have had their feeds pre run to panel location.

General discussion is boating topics only. Daily funnies, jokes and the such get posted in politics. I had intended to get the Web site changed over and refined with a few more topic catagories as the IT guy keeps reminding me. Unfortunately my mom had to move in with us as she is unable to care for...

Bruce

Welcome aboard Pete.

Bruce

Pat and I did the North/South run for the owner of a Hatt 48 fdmy for a few seasons. Painfully slow, guzzled diesel and following seas kicked our butts in Albemarle sound more than once dodging crab traps and threw us around like a rag doll. Floating condo is a great idea. Good luck with the project.

Bruce

Chris,
Welcome.
The 5.7 over the V6 is a good option and since they are popular, the pricing can be better. I never repowered the 26 so I can't tell you actual performance or fit. I've done V6 to 5.7 repowers on similar boats and ran into few issues with better performance.

Bruce

I've seen numerous brand boats used as patrol boats for water front communities. But according to rules of the road it would have to have standard red/grn running lights. The blue law enforcement lights would have been added. I too have seen the green light lenses turn to a blueish color with UV exp...

Bruce

Bill,
It wasn't uncommon to see a boat sell under survey price. You can do a search on yacht world and see what comparable boats are listing for and sold for.

Bruce

As a kid I admired the guy who painted and gold leafed the names on the back of my dad's boats.

Now they can wrap a whole car in vinyl and make it look like paint.

A lot of artistry has been lost especially here in the states.

Bruce

Few things, Make sure throttles at carb are opening all the way. Butterfly's should be in the verticle position both primary and secondary. Engines off of course. Next is to make sure tachs and engines read the same, not uncommon at all to be off. Third would be to check prop size with whats on ther...

Bruce

Very nice.

Bruce

Absolutely Carl it will.
In my case the owner didn't want to pay a dive service to change the props on a regular basis. He wanted to fish one week, dive the next, etc. As a new diver he tried changing the props himself underwater, about drowned.

Bruce

One of the first 31's I did had 170's lag bolted down to the trimmed out plywood covered old stringers when the 6lp came out. The owner complained it was slower than molasses in winter and put the 6lp engines in.

Bruce

Caveat on those engines. There is a narrow point on those engines where loading won't allow the turbos to spool up thus black smoking. Used them on a Bert 28 repower. Ran decent but slow on sea trial. Owner seemed happy. He got dive certified and loaded the boat with 3 guys and gear with full fuel. ...

Bruce

2nd boat is a total waste of effort.

Bruce

What is wrong, bearings, blades?

3k is the price for a new.

Bruce

I was told cabin house had burnt.

Bruce

That was one of my basic repowers. Had cummins triple nickels, came from Bahamas. Also installed glastech deck and boxes. Old deck was rotted plywood which was real fun getting up. With all the rush to get it done by the owner, he must have got sick or something right after getting it back. 80 hrs i...

If anyone is concerned about noise use this Colibri, http://www.academy.com/shop/pdp/aguila-ammunition-colibri-22-20-grain-rimfire-ammunition on non supressed 22. No semi, it won't cycle the action. Bolt rifle or revolver. I turned a few of you northerners on to it where ducks and geese would use po...

The neckbeards in Florida would just burn the boat to get rid of the Raccoon.

Bruce

Pete, Patrick's last 31 sold and now lives in NC and was at the June get together. Scot I believe has a 25 and is down in that area. Not sure if Mike Holmes is still running a boat> Just last week I found his web site which seems more about hunting. He was looking at selling his licenses a while bac...

Ryan,
Stuart on down is considered S Florida, can you give a more precise location as in PB, Dade or Broward.
Which engine do you have?

Bruce

Very pretty boat with the bright work.

A 350K 31 was not uncommon in the 02 to 06 years. Was involved in few, turned down 3.

Bruce

On a 31, a #8 wire run front to back will more than carry the bonding load. You can use a buss bar to tie wires together. Try not to clamp wires to objects while it's better than nothing you can lose connection easily. You can clean a spot and solder a tab onto fitting to connect a lug to. Soldering...

Either end as long as it's in the saltwater side. Usually they have a drain plug you can replace with a pencil.

Do the Mercruisers have the Mercathode system? If so you don't need to add pencils.

Not trying to be a smart ass, but I learned early on to work upside down, sideways and slither into places.

I also removed manifolds from time to time to get access.

Bruce

As long as the pump is self priming good changes are you won't need a scoop.
But I have seen self priming pumps have issue at speed and if put were turbulence at speed is a factor.
