Alternator - 351 Commander Printed From: CorrectCraftFan.com Category: Repairs and Maintenance Forum Name: Engine Repair Forum Discription: Engine problems and solutions URL: http://www.CorrectCraftFan.com/forum/forum_posts.asp?TID=48660 Printed Date: November-23-2024 at 2:33am Topic: Alternator - 351 Commander Posted By: SactownStalker Subject: Alternator - 351 Commander Date Posted: May-08-2020 at 1:00pm 1984 Ski Nautique with a Ford 351W Commander Hello! I am trying to find the part/model # for the alternator that will fit this Commander setup. My challenge is that I believe the old alternator was not marine grade as it does not have an ignition screen on the back so I can't simply rebuild it. It was also oversized in physical dimensions as it didn't even need a grounding wiring because the grounding nut was pinned directly against the block. Therefore, when I replaced the previous alternator which had died with a marine grade of the same size, the extra length from the screens prevents the lower mount to line up with the adjuster bar. Not surprisingly, the carburetor was also for a car so I am trying to give her all the TLC she needs from the beginning. Otherwise this is a very clean boat with only 540 hours on it and runs great. Thinking my options are to find an alternator that has a lower profile or to find a longer alternator adjustment bar (assuming they exist?) & a bigger belt since the alternator is now kicked further outside since it can no longer slide in front of the block as it was intended. And of course I didn't take a good pic of alternator before I pulled it. In this pic, you can barely see it on front of block, but this is what motor looks like. I can take more if they help? https://photos.app.goo.gl/LVPfZwYcngaV13xt8 Thanks, Brian Replies: Posted By: Marseille Date Posted: May-08-2020 at 2:38pm Can't help on the part number on the Alt but curious if the + wire on the alternator is going through a breaker? I don't see a voltage reg (could have been removed when going to an internally grounded alt). ballast resistor (maybe removed if converted to EI) or any type of breaker next to the starter relay? ------------- '83 SN Posted By: FLCaptain Date Posted: August-14-2021 at 5:34am RA097006 You’ll need a 1 inch spacer from the hardware store too.

I was just researching the same info for my 79 today and stumbled on this. So I figured I’d reply just for fun.
