      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

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!".
