I had been left a 15 foot speedboat when my uncle passed away that i decided
to clean up and repair, but i knew nothing about it at all when i started to
make repairs and get her ready to go back onto the water, anyway after many
weekends of rubbing down, painting and cleaning in places i did not know a
boat even had places she is ready to go onto the water............. and i
still don't know who made her!!

But i have come across a problem but i cant seem to find any sites that will
provide an answer.

How can i tell if this speedboat requires a long or shortshaft outboard??

Is there a measurement between the keel and mount that will give me the
answer??

Any help greatfully recieved.

TIA

Paul

Measure from the top of the transom (on which the outboard will sit)
to the bottom of the boat (outside distance). If it's 15', it's for a
short shaft motor. If it's 20" if for a long shaft motor.

PS ooops just realized your in the UK. What I gave you is U.S.
inches. Not sure how they measure it over there.

I'm sure there will be a convertion table i can use somewhere on the web

thanks for the help

Right. The principle should be the same as far as I know. Top of the
transom to the bottom. My guess, for a boat of that type and size,
it'll be 15" or a close millimeter equivalent, but measure to be sure.

You can adjust an outboard up or down a small amount to get the prop
and cavitation plate to the right depth. They all need a bit of
adjusment anyway. And with a jack plate, you can even mount a 25"
shaft on a 15" transom without rebuilding the transom although it
might (maybe) require some sort of transom reinforcement. Trying to
put a 20" shaft motor on a 25" transom would call for transom surgery
though.

2.54 cm = 1 inch

Set the cavitation plate even with the keel. You can then jack the motor up
as much as two inches. Be sure to run the boat allot at each position to
evaluate the handling!

Sooooo....standard transom/shaft measurments are 38.1 cm and 50.8cm??
Are UK boats and motors listed at that in the spec section of their
literature?
Just curious.... seems odd as a standard anything although I guess if
they sell much to US customers, that's what it'd have to be.

Rick

Yes, the UK boat specs are the same but are expressed in SI units instead.
