Here are two pics of an 08 50hp E-TEC on a 1995 13ft Dauntless, Based on some info from this forum and personal observation, the engine is clearly too low. It is currently mounted on the bottom holes. Bases on what you can see, do I need to raise it one hole or two.
Thanks

Ditto, If engine cavitates on turns on plane go down one. Don`t over rev engine.

Every boat engine I have owned was mounted with the cavitation plate even to the bottom of the hull. This provides good flow to the water pump and control of the boat. I would check with your dealer -- if some of you go higher it must be okay. Just be careful I do not think BRP is going to replace your engine if you blow it up due to the wrong mounting height.

1 to 1 1/2 inches above the keel is the general recommendation for a whaler.
Keep in mind, you will gain 100 ~RPM for each hole you go up so check your WOT rpm's and speed.

Just a quick update on progress,
Moved the E-TEC up one hole and it made a big difference, rpm is now 5700, less torque steer and much better bow control and trim range. It is amazing what 3/4 of an inch will do. It was clearly mounted way too low. Thanks for the opinions guys!

Even though this article is about engine propping, it has a clear description with pictures of checking proper engine height while underway. Pretty useful and takes the guesswork out of the process....
