Cool
project. I’m in Toronto so cant help much. I have a sailboat and
Dinghy in a club but moved from a SeaRay Sedan with twin diesels to a cute 40hp
Yanmar.
I’m familiar with your Chris. I’ve boated beside many of them. There are two huge issues to talk about. The stern drive and the old block. The did build it with twins but rare. They are not great on gas but room to improve the
engine. If it’s an early
OMC drive you need someone really clever to help you. If it’s a Merc you’re golden.
The intake manifolds all crack at the choke. The choke was junk anyway. I’ve built pairs with edelbrock performer 650 Holley vacuum secondary with the brown tow truck cam. Holley has a
marine whistle kit and extended float bowls extra long transfer tubes and brass floats. Rare so I’ve just got them from junk yards and built them.
Merc did nothing on the old heads so up to you but the rockers and pushrods are likely shot and
oil seals on heads. 160 roller rockers and rods
When you get around to looking at those big sliding window photograph and measure any surviving nylon clip. I have the data for most of these clips in 3D print and can make you some. The
radar arch was a cool expensive option. Makes me guess it may be a twin. They can damage the laminate in the coach roof balsa. Check for soft spots.
Some years the swim platforms were terrible.
Plywood and poorly sealed on the underside. I helped replace one with a
teak one. Welcome back
