OMC to Mercruiser

[lifestyletoys]

I am in the process of converting the old Stringer mount OMC to a Meercruiser/Alpha1 drive.Can anyone direct or inform me on where to locate the specs with regards to engine mount heights,transom cutout and alignment?<br />I could build a jig based on some rough dimensions taken from a scrap vessel but would like to at least check this against known good measurements.<br />I will post the updates as this project progresses since I am sure many have attempted this in the past using different methods.<br /><br />Thanks to new epoxy resins,advanced materials and the information gathered on the iboat forum, this project has become easier to undertake by a DIYer.

Sorry I can not help with the infomation you seek but since I also have a 1980 OMC Stringer Motor and love it I would sure like to here what troubles you run into and final cost. I have checked at the boat shows and been told would be Around $10,000 US. That included a New Motor and outdrive.

Re: OMC to Mercruiser

I've done one,+ am about to start another... what i do is cut the "plug" out of a donor boat...Make sure you cut it Bigger than you think you need...as long as you can reference the keel line, that gives you the "X" dimension... on the Hi-Liner we just did, we opened the "hole" out another 3" or 4" to find Good Wood... then went back with plywood,+ epoxy to get it filled in...Then opened the holes we needed with a drill, saw-zal, roto-zip, etc. using the donor fiberglass plug for guidiance....<br />for the motormounts we "Hung" the motor in place,+ built to it.... <br /><br />Boatist,<br />i'm using alot of ebay,+ scrounged parts... i "Could" make it run for maybe $1000. But this next boat is my Dreamboat..... it'll be going together as a fresh Alpha1,+ a fresh SBCmerc. power...... For Now......
