Hi all,
I’m new to this forum but have a question. On my 70hp Johnson 70el78c on idle and part throttle motor sounds super healthy and has recently been rebuilt. When going to WOT motor bogs down and never planes out. I have a 13 x 12degree 3 blade on now and that prop seems normal. That motor was put on a 15+foot 1978 fiberglass boat and don’t know if is to much boat for the motor or should I try dropping to a 13 x 10degree prop or 14 x 10degree 4 blade?
