reverse rotation?

my 1979 martinque needs a new starter and i can't find any markings on motor (351W commander) about rotation. plug wires are off so please don't suggest that easy answer. it has a right hand prop so i belive it is reverse rotation (non regular automotive) starter. does anyone know for sure?

can't seem to post a picture using upload but it looks just like this one:http://www3.towerhobbies.com/cgi-bin/WTI0001P?I=LXE496&P=8 i know it's off a hobby site but it is the same as looking at mine from rear of boat.

pointer is on right when looking at crankshft pulley (5-8 side of motor), reverse rotation?

the prop DOES NOT! it could be a reverse rotation transmission. with the pointer on the right tht indicates its a left hand rotation engine. the common one luckily.

Not in a '79

1st gen martinque?

Mike,
What's going on with the starter?

can we have a pic of the timing indicator??

Well, you never commented on why you went looking for a new starter! Did you do any checking for things like volts getting to the starter or are you just throwing parts at the engine?

Another holley 4010.

Hijack over.


OP,

The info you seek is in the 3 previous posts.

Velvet drive with a right hand prop will indicate points to a reverse rotation engine. Velvet Drives running in forward spin the same way as the engine. Velvet Drive and v drive are not the same terms. Velvet Drive is a borg warner transmission. A v-drive is a gear box that connects a rear facing rear mounted engine and transmission to the prop shaft. Long story short is if this was running around the way it sits you need a reverse rotation starter.Good Luck!

oh. about that. after a 6 hour trip to NH the battery shifted forward from sitting against the silencer and i saw the start capacity. Its a 685 Cold Cranking Amp Battery. and CC's stupid battery cover says you only need a 360 CCA for a 351W and a 470 CCA for a 454 Big Block!!!! those numbers are way off.

Put a shunt on the cable, crank the engine over, connect the meter before you open your mouth! Sorry but get some good amp readings first I would go by the OEM specs first.

Well, we stole the mini high torque starter off the Supra and put a new one on the Supra. The old plunger starter had a short and would do fine when cold. but after boating around for a while the heat from the engine was enough to prevent it from being able to turn the engine over. Because of hard starting the previous owner put in a freaking huge battery! volts only drop to 10.5 when starting and holds 11.5 volts after sitting all winter still hooked up. its nice to have a big bat. so we can listen to music and have the lights on for floating around at night and not having to worry about starting the boat. (we redid sound system and have a 1600 watt amp)
