Took my '84 Montauk over to the marina this morning to have the old Marina motor pulled and the new one set in place (easier to pay a few bucks than to rent a hoist for a day). Anyway, we can't see how in the world there is room to put bottom bolts in the '91 Evinrude 90 I am mounting. If I put the motor one hole down as recommended, any drilling for the bottom bolts would still be under the splash well. Can someone please share close-up pictures and measurements? Please send to billh1963@cox.net or reply to the post.

Thank you!

Bill,

You need to use the "blind holes" in the Evinrude. These are above the lower bolt slot and allow you to bolt from inside the splashwell.

The cap screws (bolts) simply thread into the threaded portion of the Evinrude's mounting bracket. The blind holes are provided for for exactly this situation.

Here is one set of photos that I can think of that shows what it will look like. http://www.sisqtel.net/~jkriz/Montauk/montauk.html I am sure there are photos in the Cetacea section as well.

I feel stupid but I wonder how the guy at the marina looking at mounting the motor will feel! Thanks, Tom!

Bill:

I had the same problem. Instead of mounting a new engine using the old blind holes, I added a 4" CMC set back plate. The plate is mounted to the transom using my existing holes, and the engine mounts to the bracket using the standard mounting holes on the engine bracket, not the blind holes. The plate allows you to move the engine up and down to your liking, and you do not need to drill any new holes in the transom.

The two piece adjustable manual has 5" of slot adjustment at the motor mounting bracket and 1-1/2" of adjustment at the transom bracket. After height adjustment has been made, tighten the four bolts on the sides to 100 foot pounds to hold the position in place.

The CMC 4" set back plate does not come pre-drilled for the lower blind holes, so you will need to mount the bracket to the engine, then the engine to the transom (Using only the upper mounting holes.) Using the existing blind holes in the transom as guides, score the bracket using the bolts that comes with the bracket (or an awl if you prefer.) Remove the bracket from the transom, drill the appropriate holes in the bracket, and remount.

Don't forget to re-seal the transom holes, and provide anti-corrosion measures for the stainless bolts when they contact the aluninum set back plate and motor bracket.
