Mike, it's far cheaper to just buy a new outboard, than any major rebuild. A careful internet search will yield some places with a small inventory.
You might have settle for a different name on the cowl than you are used to. But most of the small outboards are made by Tohatsu anyway, plus Honda and Suzuki still build their own. AFAIK.
Automotive engines? It is real tough to beat a Detroit crate motor. Unless one is looking for serious performance upgrades.
I am far more familiar with GMC V8 engines than the alternatives. But am amazed that one can buy a stock 5.7 Chevy for around $2k, or bump the HP by almost 100hp in a GM factory built engine for about $5.5K
I was about ready to pull the plug on an HT383E for my 96 Vortec 4x4. 323 HP for $5400, and bolts right in under my manifolds. But I stumbled across this 01 GMC W/ 130,000 on the meter for less.
It always has been: "How fast can you afford to go?"
