Engine rotation question
 

Good Morning,

I have an 88 Supra with a 454. Had it on the water Saturday when the
starter quit working. Replaced the starter and now it cranks forever
but won't fire. I have been looking into the possibility that the
parts gentleman sold me the wrong starter, since all I am doing is
blowing air/gas out the top of my carburetor now. I'm thinking I need
a starter that turns in the opposite direction. There is a tag on my
engine with a model number, which when referenced to my owners manual
says I have a left-rotation engine. But I don't know if that is
looking from the flywheel end or the damper end. From what I have read
it seems that engine rotation is almost always determined from the
flywheel end. Anyone confirm this? This is an inboard boat. Thank you
for any help you can offer.

Yup. You bought a CW starter. Take it back and exchange it for a CCW
starter. CCW is considered standard rotation.

Engine rotation for inboards is always at the flywheel end. Most single
engine inboard boats use left-hand engines. You are probably correct in that
the starter is the wrong type.

Thank you both for the replies. I'll go exchange the starter.

Jim brings up a good point... and it's hard to remember which way is
"standard".

"Reverse" rotation is a right-rotation engine as viewed from the
flywheel OR prop on a direct drive or V-drive(with the PTO off the
flywheel).

CW starter for standard rotation...
CCW starter for reverse rotation...

And then you have rear entry starters which add to the confusion.

Good news. With a different cam shaft you could probably have gotten
it to run backwards. :-)
