OMC outdrive electric shift wire grommet

thingiverse

This is a grommet I designed for an OMC outdrive electric shift wire cable harness. GLM Part Number: 27931; Sierra Part Number: 18-2192; OMC Part Number: 379628. This was used on most OMC 120, 140, 165, 170, 190, 225 & 245 Hp Stern Drives between early 1970 to late 1980's. Check it out here: http://amzn.to/2h4ROQs. It's common for people to break these trying to remove the out drive, or for them to just short out from wear. This wire goes through the transom and needs to be sealed. We had a short in ours that was in the molded grommet part of the wire, and because a replacement harness is so expensive I decided to make my own out of things I already had so I could go fishing. I used an old 2 wire US 110 plug off a broken Ryobi charger, it's a common wire like this one: http://amzn.to/2h3sQzo. I cut it to length, used some Yamabond in the area that the grommet will be located then took about around 8 inches of heat shrink tube: http://amzn.to/2hMXgoh and went up and over the Yamabond and heated it to shrink down over Yamabond. Next I printed my grommet out of Ninjaflex SEMI-FLEX filament: http://amzn.to/2i8eGe2. I then covered that now shrunken heatshrink tube with Yamabond and ran the printed grommet up over the tube, it should be a snug fit I had to warm the grommet some before going over the heat shrink, the Yamabond should act like lube. But test fit it first if its too loose add another layer of heat shrink and Yamabond like the first and try again. Install some new plug ends! The ends of the wire are just common bullet connectors like these: http://amzn.to/2i89reb. Cover the grommet with Yamabond and lace it through the transom and press the grommet into place so its flush like the original. Now check for leaks, mine seems to still float, so now let's get back to fishing already....
