Author Topic:   Motor tilt vs performance

I own an older Johnson 100 hp (on a 16'7" Whaler) without electric tilt and trim. As you know, there is a pin for tilt adjustment with 4 four holes to tilt the angle of the motor.

With an electric tilt, I would tilt/trim the motor out as I reached planing speeds to maximize speed vs rpms. I would also have the ability to tilt out if I were in shallow drafts.

As for the manual tilt on the Johnson, what is the best all around setting for the tilt, nearer the boat and more vertical or farther from the boat and more tilted. Or perhaps the better question, what is the effect of the different settings on overall performance?

If it is a factor of the question for the best tilt setting, I mostly fish the inland lakes and streams of Grand Isle, LA, where the shallow draft is preferred.

Kind regards.

From the several manual models I have had in the past and reading the manuals that came with them, the Pin is set correctly when:

1. The boat is not plowing - pin too far in
2. The boat is not porpoising - pin too far out

Once you get the pin in the correct position, you are set. Of course when you change the load in your boat, you may have to change the position of the pin.

Some smaller outboard models had a shallow water tilt mechanism. I don't believe the 100 has that feature, but you could move the pin all the way out for slow speeds and shallow water, and then move the pin back to your full running position as stated above..

One of the first things I did on my 70 HP Evinrude 15 was add Trim & Tilt as the manual tilt was a real, all around, pain in the neck. Even tilting it up to the trailering position was not easy for me and it was only a 70...

Used Trim & Tilt units show up on eBay... I added one on a friends 70 HP Evinrude and it was around $200. He was lucky and purchased a brand new one on eBay for that price.. It would make your life much easier and save plenty of back aches.....

Thanks Joe, I agree. That would be money well spent, in boat performance and back safety. Heads up on the Ebay search!
