Perkins 4.154 starter question

Recommended Posts

My Perkins starter motor is poorly with some corrosion on the front of the shaft preventing the engagement of the small gear when the solenoid is engaged. I am hoping to get it put back into action but would like to buy a new one and keep the old one as a spare.

When I search for a replacement on the internet I keep finding what I think is a smaller geared starter motor.

I had not seen such a thing before. Does anyone have any views on the use of geared motors as starter motors. 

My current starter looks like this  and the new ones on offer look like this.

Hope that helps a little.

I changed from direct to geared on my old (1979) Cherokee Chief that had an AMC 360 (5.9 litre) gasser, and it was a major improvement. No experience of the geared units in a marine application, but once you keep your engine compartment reasonably dry and well maintained, I don't see an issue.

The geared type will draw considerably fewer amperes than the 'old-fashioned' version, and that is likely going to be of benefit in a small craft application.

Thank you for the link. That does reassure me that geared is OK. 

Interestingly the geared ones on offer are cheaper than the non geared original.

Most likely because they are now 'standard'. CNC and mass production based on demand would skew things that way. If you have spent time down here, you'll know what we mean when we say "Go through hard!".
