what hole do you have your outboard mounted on the transom? My very sloppy install from the dealer is the top hole. Plus the guy didn't use the blind hole for the bottom bolts. He frigging crooked drilled holes into the well. He said the new motor bracket didn't have blind holes. As soon as I pull it out of the water i am going to pull the motor off a little and check. Every specific question I asked the guy about the motor has turned out to be wrong. I pointed right at the water indicator and asked if this new motor had the new flush inlet for a hose and he said no. I asked him what gearcase oil, Hi-vis or HPF and he got it wrong. I asked him why my water pressure gauge wasn't hooked up and he said there was no outlet. So basically I think I have two bonus holes in my transom from stupidity. Back to the main question. What hole are your motors on? Masbama, where's yours? top hole or one hole down? BS where do you think is the best place to start? any input appreciated.

On both of my Montauks which both had Johnson 90's, though older (1982, 1986) the motor was mounted all the way down using the blind holes. This is not to say your motor wont work well or even better mounted one hole up, but at least until the late 1980s the convention was to mount it all the way down on a Montauk.

As I recall the blind holes are visibly evident from the side of the mounting brackets. There is a bulge where the blind holes go. I have no idea if the new motors have this very useful provision.

Who installed your motor? I'm in Seattle and am curious. Please tell me it wasn't Bay Marine in Suquamish.

Your new Johnson 90 motor has the blind holes. My motor is mounted all the way down such that the bracket hook is almost resting on the top of the transom.

My engine is different (70hp Evin) but was mounted (by original installing dealer) in the 3rd hole down. Worked beautifully. It's now mounted on a jackplate and rides much higher, but more on that later.

I would suggest moving it up to the 3rd hole down as a starting point. If it works, fine. If not, drop it a hole. But from the 3rd hole down your lower bolts fit at the top of the lower mounting slot. Next step would probably require blind hole use. So, you just might want to start out at the 2nd hole down, use the blind holes, and call it a day.

Harpoon, too many options, Harry

I would NOT use the blind holes. I owuld mount about an inch or more above the transom and use the slots provided. My lower bolts are in the bottom of the well.

Relax Tom I'm not suicidal. Living here on Bainbridge Island, we long ago learned the "Bay Marine Lesson". I drove down to Scappoose in Oregon to Channel Marine. No sales tax and they didn't want to charge 880 bucks like jacobsen or 1000 like mercer.

I'm like whalerron, Raygun. I have mine set up the same. I feel there is no need to mount this engine any differently; it works perfectly with this basic set up. Sounds like your dealer is a dum-dum.
