OMC outdrive electric shift wire grommet by motojeff

Last crawled date: 3 years ago

This is a grommet i made 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

Its 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 id 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, its a common wire like this one https://www.amazon.com/ELECTRIC-SHIFT-ASSEMBLY-GLM-Number/dp/B004AQU8X4/ref=as_li_ss_tl?ie=UTF8&qid=1482181490&sr=8-1&keywords=379628&linkCode=sl1&tag=wremot-20&linkId=2d8b4ef82d31687c4e435fcc86eba6db
I cut it to length, used some yamabond https://www.amazon.com/ELECTRIC-SHIFT-ASSEMBLY-GLM-Number/dp/B004AQU8X4/ref=as_li_ss_tl?ie=UTF8&qid=1482181490&sr=8-1&keywords=379628&linkCode=sl1&tag=wremot-20&linkId=2d8b4ef82d31687c4e435fcc86eba6db in the area that the grommet will be located then took about around 8 inches of heat shrink tube https://www.amazon.com/ELECTRIC-SHIFT-ASSEMBLY-GLM-Number/dp/B004AQU8X4/ref=as_li_ss_tl?ie=UTF8&qid=1482181490&sr=8-1&keywords=379628&linkCode=sl1&tag=wremot-20&linkId=2d8b4ef82d31687c4e435fcc86eba6db 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. https://www.amazon.com/ELECTRIC-SHIFT-ASSEMBLY-GLM-Number/dp/B004AQU8X4/ref=as_li_ss_tl?ie=UTF8&qid=1482181490&sr=8-1&keywords=379628&linkCode=sl1&tag=wremot-20&linkId=2d8b4ef82d31687c4e435fcc86eba6db
i then covered that now shrunken heatshrink tube with yamabond and run 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: https://www.amazon.com/ELECTRIC-SHIFT-ASSEMBLY-GLM-Number/dp/B004AQU8X4/ref=as_li_ss_tl?ie=UTF8&qid=1482181490&sr=8-1&keywords=379628&linkCode=sl1&tag=wremot-20&linkId=2d8b4ef82d31687c4e435fcc86eba6db
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 lets get back to fishing already....
