water in cylinders

+1 wrong starter... I have a 1975 CC Mustang with 990311R11 motor and it's a 307 RH. Rotor turns the same direction (clockwise) as the crank (supposed to) when viewed from behind the bell housing.

Firing order: 12756348

Wrong starter

We rented the boat, for 2 weeks, in 2012 and everything was great. We bought it in spring 2013 and used it 3 or 4 times thru the summer. At the end of summer started having hesitation and bogging down and starter began to drag. I guess I need to find the correct part number for a Right Hand starter according to all the posted response.

If it's a 350 block, $5 says it's not the original. The 305/307 and 302 were the options for the M17, and that lines up with the 225hp rating. The 350 option was higher (250-260, iirc). Someone could have dropped in a 350 block pretty easily an kept the original OMC engine tag.

If the engine that's in the boat ever pushed it under power, then it has to be reverse rotation and you've got a LH starter trying to spin it backwards. If someone installed a LH 350 and never got the boat running/driving again, there are all sorts of things that need to be addressed. Better figure out which way the engine spins and cross your fingers it's just a starter swap that you need.

The 3970014 casting number indicates its a 350 block. That casting number was used by GM from late 1969 to 1979 and came in both 2 bolt and 4 bolt main configurations. 307s had a cylinder bore of 3.875" while 350s have a 4.00" bore. Don't think that casting was ever used for anything smaller than a 350ci engine. Must be a RH rotation 350ci 225HP engine.

Picture says that's a RH rotation prop. Should be rotating clockwise standing behind the boat looking forward with the transmission in forward.

According to this site, it is a 225hp model. I think '74 predates the 305 so it's probably a 307.

That's a 1974 220HP RH rotation engine (cars are LH). The R in the 990311R1 model number gives it away.

Correction engine is stamped with numbers 3970014

I agree Gary if someone is lookimng for an out of production starter.

In this case a 350 SBC is very common and can have a couple different starters in each rotation. Especially if it's in a boat that didn't have that engine option to begin with.
The very first question out of the sales persons mouth should have been RH or LH? Then a second question might have been top mount or bottom mount? That would have at least alerted the OP to do a little more research if he didn't know the answers before buying. I guaranty buying from someplace like SKIDIM or Zach will get these questions every time.

Now having a different nose cone and then swapping them out is a "shame on him". That should have raised a red flag immediately but I won't go there. Learn from it Grasshopper.
As a last resort, removing the starter and taking it along with him might have been a novel concept but a complete moron behind the counter could still screw that up.

Lies!!! I sourced a HM starter as well when Dave needed one.

Haha good idea Eddie.

Gary is a wise man.

I bought my boat cheap because someone did the exact same thing.

Need more info, mustangs never came with a 350 v8 so we dont know what you're working with here
