First of all let me thank you all at IBoats for this incredible forum, what a valuable asset to the boating enthusiast.
I recently was given and brought back to life a Four Winns 170 with a Mercruiser 165, 224ci 4 cylinder that had been rain flooded. Did not rebuild it. Just got it unstuck, many oil changes, rebuilt the starter, trim pump and shift/ throttle controller, complete tune-up, cables, impeller, all in all about 170 hours in labor & cleaning. It had been garaged most of its life accept for one unfortunate wet season when my son-in-law left it out in the back of the barn without a cover and did not pull the plug.
I found this forum to help me with the confidence needed to take on my first marine project. And I was super pleased with the final result, untill my son-in-law also was pleased with my progress and told me "I never gave you the boat"...bummer right? I love my family more than some stupid boat, RIGHT? OK I'M OVER IT ALREADY! !!!!!!!!!!!!
Now, I have the desire to rebuild a motor.( Note: I have rebuilt a 302 and a few VDUBS in the past. I'm rather mechanical and would rarely hire anyone to do anything that I haven't given it a try first)

Not having a boat (YET) I'm curious as to what would be the most practical motor to build. One that would not limit my choice of boat too much. I would like to eventually buy a 17'-20' cutty cabin I/O with a bad motor.
I plan on using it for family on Folsom Lake and fishing the Sacramento River, Delta, And occasionally out of Bodega Bay in Northern California Coast.
Just throwing it out for some expert advice... looking forward to hearing from you all...

Get the right boat first. Something with a small block Chevrolet. Common motor, easy to rebuild

I thought someone would suggest getting the boat first... and I know I should. Ok... how old of a boat... how old is too old... I can't afford a fancy newer model... I don't want to have issues with older outdrives and newer rebuilt moters and not finding parts.

Do some learning on how to check a hull. You want one that's ready to go if possible. Find out how to check for rot and where it occurs. You can find newer boats that are bad, older ones that are good. And everything in between.
Also I agree wholeheartedly to try for a 350. Most of the engine bits are Chevy.
If you find one where the block will be disassembled, look into pistons that will optimize quench. They are out there for the same money as the dished poor quench ones Chevy assembles with. Good quench is free horses and fuel economy.

I wouldn't look for a motor to rebuild, suggest looking for a boat that is running. You can find an older boat in decent shape fairly cheap. Find a newer boat with a bad motor only guarantees it has a bad motor, there could be other things wrong which could cost more.

Sure hope the in-law at least paid you for fixing his boat
