Sort of a two-parter.
I realize this isn't a particularly strong engine, but feel like it
still doesn't perform as well as it should.
A) Does anyone know what the factory prop was for this engine (1990)?
Depends on the boat. WOT rpm range is the important number when
buying/sizing a prop. For most fiberglass boats, should be 15" or 17"
for lighter hulls.
It's a 17 1/2' Sunbird (fiberglass). No longer made. Haven't had it
out this year, and can't recall what RPM it was hitting. The problem is
that with a decent payload (~600 lbs), it's very difficult, if even
possible to get on plane. I often have to hunt for another boat that's
throwing a good wake and "surf" its wake to get enough speed to get up
on plane. Actually a skill I got pretty good at, but a pain even so.
(B) Does anyone have any suggestions for getting a bit more HP out of
it
for a reasonable price?
This engine is only 95 hp in a car, w/ a Holley/Autolite 2bbl carb, &
OMC says 120 hp in your boat, but can be 205-210-215 hp in turbocharged
form - google "Mustang SVO" for more info...
That's the sort of stuff I had already found. Can't justify spending
that sort of money on a pleasure craft. I'd just as soon sell it and
buy a bigger one if that's what it's coming to.
Have searched for electronic ignitions, but the
few I've found out there are stupid expensive.
Check "Retro Rockets Pertronix" in a web search.
It won't give you much if any perfomance boost, but your state of tune
will be more consistant.
Thanks. I'll check it out.

A friend of mine had the same problem with an identical Sunbird. His
solution was to place 200 pounds of weight in the cabin at the front of the
V berth.
