Chev starter motor problem.

[Kev80]

Does anyone know much about starter motors ?

Im having a problem with the old 350 Chev engine in my ski boat, it realy labours to turn over & doesnt quite get enough revs to kick over even when using my new truck battery from my 80 series.
Cables & connections seem ok.

The thing is that when i take all the spark plugs out it spins over fine.

Is it possiable to have a starter motor fail under load but ok otherwise ?

I cant think what else it could be !

Chev starters have always been crap, go and buy a new gear reduction type starter ~$400 and it will spin over like no tomorrow. Ive had Chev's in 4B'S for 20 years now and always had probs with chev starters untill i used a reduction type from about 10 years ago and have never looked back.

Yep Wally has got it. The Standard Chev Starters are hopeless with a decent engine.

There used to be a company in Aus somewhere that was making the mounting face for a reduction starter. And you just used a Toyota Reduction starter body and solinoid and fitted the supplied drive gear. Was fairly cheap too but cant remember where they came from. Looked just like a Tilton Starter when assembled.

Thanks for the help.

I have heard of reduction starters but never seen one, is it a smaller unit or a reduction in gear size, whats its purpose ?

Where is the best place to buy one as its usually cheaper to order things than to buy them here ?

Ruff, the modded starter sounds like a good idea but because its in a boat i dont have much room under the engine to muck around so might not go this way.

Any V8 performance shops sell them i have brought them from Eagle Auto Spares (03) 97925544 they stock them in Vic and they can send you one they have an outlet in Sydney and believe are or have opened up in QLD somewhere.
