this sound something similar.
Firstly new to these engines and ribs, getting up on plane.
Had a smaller boat with 15hp so just had to drop engine and off i went.
This is what i did:
Started engine set off up the harbour 1,000 to 2,000 revs, bow up so me not being use to it trimmed out instead of in, increased throttle past 2,000 revs and engine trimmed in towards transom, tryed trimming out again and the same thing happened. Then just thought this must be a safety feature on the engine that when you go past a certain revs if the engine is trimmed out too much it drops. maybe not but hope thats all it is.
i will do it the correct way when im out the next day and we'll see
