Hello,
I usually don't have to create posts, if I look hard enough a million people have had the same issue and recommendations have been made. But, I cant seem to find anything regarding my exact situation.
I have a StarCraft Super Sport 16 foot aluminum with a 1970 Johnson 60hp motor with an aluminum 13.75 x 15 prop, an SE400 Hydrofoil and anti-ventilation plate positioned 1.7 inches above keel.
The boat has manual trim, if I trim the motor 4 holes down from the top on the mount it works well but a little slow (27 Mph)
If I run the motor 3 holes down on the mount it works better (30 Mph) but at the very top of the acceleration in a straight line I hear what can only be described as a faint hollow howl sound , barely noticeable. The same could be said for turning left. But, when I turn to the right the sound is more pronounced, almost sounds like a jet engine.
Ventilation?
My issue is I experience no slipping, no rpm increase, and it doesn't slow down at all.
I guess my question is, Do I have to drop it a notch for the motor's sake and give up some speed, or can I safely run it like this?
Thanks
