I have a 1971 Sport 13 with a 35HP Evinrude. The motor is on the first tilt hole position. There are 5 positions. When you run at top speed, it seems to be pushing water and not the boat. What is the best position?

It depends. You are going to have to experiment to find out what hole is right for your setup. It depends on the location and how much weight within your boat. The location of your gas tank, battery and gear will make a difference. How many people in your boat and where they are sitting will make a difference. Some days a different hole will be better than the last time out.

That being said, on my 13’ I rarely change the trim. I have it set on the middle hole and usually just move gear and people around.

Without power T&T this is the best method I have found too. Maybe a different hole, but it's a pain repositioning that pin while underway. Almost ropped mine in the drink the other day. That would have been real bad.;{.

I too have a 13 footer with a 35 HP Evinrude (both boat and motor are 1978, I believe). I just noticed this weekend that the motor is in the middle (or "third") hole, of the 5 holes available. I had been thinking of experimenting with different hole positions, but the boat is so perfectly balanced with this set up that I have decided "if it ain't broke, don't fix it".
I had also been toying with the idea of putting a 50 HP Mercury on this boat that I have (with power tilt/trim), but the notion of seperating these 2 old friends (the boat and motor combo) seems inappropriate to me now.
This boat gets up on a plane instantaneously, and shuffles along at 28-30 mph (guesstimate). While it would no doubt be faster with a little extra horsepower, it would not be as well balanced or as well behaved as it is with the 35 HP. Sometimes, it seems, less is more.
Try the middle hole, and let us know how it works out.
