Has anyone tried one of these starters? I have been getting my current starter rebuilt about once a year and thought I would buy a new one this year. I am looking at a Mallory or this one at about a third of the price. Probably Chinese made.
The motor that is currently in it is a 50-29105. I also have a delco 1113569 and they both seem cross to this one.
I have had it rebuilt at three different local shops. They keep going out of business. The symptoms are always the same well not the first time.
The first time the starter drive needed rebuilt as the spring was broken and it was turning over too slowly with no v drop between the battery and the starter as well as on the ground side. That time I bought a used starter off the internet and took both to the rebuilder.Telling him to make one good one from the parts as the original also had a cracked mounting ear. That rebuild lasted a couple of years.
The symptoms each time after that would be it suddenly would not turn over the engine or just barely again with full battery voltage and no voltage drop on the cables. The starters would also smoke. I believe the rebuilds I was getting were just brush replacements. They might have also cut down the mica on the armature but you can only do that so many times. To be honest only the first rebuild cost me more than $50. The receipts just say repaired and lubricated. although the estimates were higher.
I also believe that I contributed greatly to there demise. Each time I had ran the battery down a week or two before by trolling on the batteryubtill it was down to 10 or 11V. Then cranking it on a weak battery which will cause a high current condition in the armature due to it stalling giving excess heat. That Combined with an armature that has the insulation deteriorated over time can cause a few turns to short out.
The "offshore" replacement units aren't all that bad of a deal, but you usually get what you pay for. The quality is surprisingly good (to me anyway, I expected them to be junk!) but the warranty is usually only 6 mo.. I've run them before, we had one on the shelf and the ARCO Marine unit (O.E. quality) was out of stock at the time. I've heard good reports on the Mallory unit, but have no first hand knowledge of them. Wilson is another brand that usually offers O.E. quality rebuilds, but their pricing is rather high.
Randy (63G3) has a good point about the rebuilder, a good one will go all the way through the unit and return it to you in truly "like new" condition.
You may be on to something with the low voltage situation, maybe time to consider a separate battery for the trolling motor? (Or more accurately a separate battery for the starter, run everything else off the "aux". battery.) That situation (low volts) will cause the early demise of even the best quality starters.
