It was your great uncle boat who passed 10 years ago. Its been sitting under a tarp in the barn. You inherited the boat when your great aunt just passed away and you finally trailered it to your house to uncover and it's actually a beauty. a little dusty but nothing a little elbow grease won't take care of. pretty soon I hope to run through things and fire it up and get it back on the water and enjoy the time that me and my great uncle used to spend on it. Also can people tell me where to start or what to look at first?

do your self a favor and replace water pump in outdrive and take a real close look at the bellows and if they are hard or have cracks in them replace them.
 
Good Call. Not, however my first rodeo. I tried to buy this boat in the early summer. it fired instantly and sounded like a new car. interior and hull in mint condition, out drive looked new. when I came back to get it, a guy was counting cash on the table. 2.5 months later I see it on Craigslist. Asking much more then he paid. then its lower, then lower, and I finally traded him a cheap motorcycle for it. I expected the engine would need help. I have about $350 into it. Interior is still nice, hull no damage, but... the fool tossed it in the water as it set and ran it. of course the impellor fell apart and he smoked the engine. toast. All the boots are bad, but I expected it. I figured from his story the engine was junk but I don't care. Its the boat I want. I will be resealing the outdrive, new gimbel, and a 69 351W 4 bbl engine, I had built for my truck its pushing around 300 hp. But its mine on the cheap, nice shorelander trailer, and a bunch of gear and canvas.
 
Youre putting a truck engine in it?

69 351w from a 69 LTD. its got piston oiling heavy duty rods, 10:5 to 1 stock, new pistons, rings, fresh valve job, RV cam, 85 HO heads, double row timing chain, 650 holley dual feed, aluminum intake. I beat a 5.0 mustang with this engine in my F250. I suspect its capable of moving the boat.
 
You may want to rethink that strategy. A boat motor similarities to a car or truck motor stop at the block and pistons. If your vehicle motor is that good I would try to sell it or swap it for one set up for a boat.

Aren't the fit tolerance on a boat motor different do to the fact they run at a cooler temp?

You will probably have to change the cam to a marine cam that will generate the right torque that is required to get the boat out of the hole.If you are using a mechanical fuel pump it will need changed out for a marine style pump and that goes for a electric pump also_Or you can say the heck with all those marine regulations and drop the really good car motor in the boat that you could sell for good money on ebay or craiglist buy a marine motor all set up .Oh I all most forgot the ignition system should not be used either along with the street carb or the alternator unless you like gas fire balls.

Besides my brother being in the Coast Guard 4 years, and 3 of my family being commercial captains in Alaska, I have been a mechanic for over 35 years, and owned a lot of boats. I know the laws and regulations regarding Marine engines. I also know my 69 351W engine bottom end is as strong as any engine specified by Mercury. Every marine certified part on my 302 will fit on a 351W. Including the marine cam. Honestly I have been studying the mercruiser product for several days now, and I find it childishly simple. Being a Mercedes Benz factory trained technician I have seen a few different systems in my days. An RV cam is designed to produce maximum torque as low as possible, and run up to 5500 tops. That's all I want in my boat. It idles perfectly.
 
Cyc. at no time did I mean to question your abilities with your back ground. You know that if someone said they were going to use a built street motor in a boat that the red flags go up. Sorry for jumping to a conclusion It is a knee jerk reaction this is a topic that comes up time and time again here on this site people wanting to save a buck by using auto parts.
 
Well post some pics of this thing!!!! Otherwise you dont even own a boat.

Don't forget to add little things that make boat maintenance easier:

Transom plug oil drain hose
Remote oil filter kit if needed
Engine block drains, etc.

Great looking boat
 
final diagnosis of the 302. prop hub spun out at full throttle with unskilled operator at helm. over rev floated the channel rockers, and dropped 2 valves. I am not sure if the 302 even with smog pistons can take that without holing a piston. SO out it comes, I have everything to install the 351. the 351 vs 302 in passenger use is night and day, but I realize that 302 had a steel crank, 4bbl heads and a fancy cam. I will just sell it in pieces, as I am sure one or 2 used pistons and a set of new rings it will be a perfect short block. maybe the heads will live, time will tell.

Well get your 351 in there and get it running.


Ps whats a fancy cam?

just a marine cam, as powerful as possible with smooth idle, not much overlap or advance however. pulling the head today to see if piston is ruined. if not I will put a new valve in that hole and run it.
 
Great looking boat ... classic, clean lines. Hope see more photos as you bring her back to life. Repower is an opportunity to experiment - good luck - sounds like "motors" are your thing.(I prefer electrons) Hope you will contribute some of that expertise here on the forum. Check out the Hole in the Water group and Classic SeaRays - centered around maintaining and restoring some of the older boats.
