This evening I have checked ratio and I have 1,50.
Also messured Toe in and that the trim indicator is synchronized between starboard and port.
next thing will be to try another prop kit.

I had the exact same boat with exact same setup. Ran 88 all day long. The 525's should turn 5300 easy with 32P Bravo 1's. The fact that the starboard is only turning 5000 is definitely an indicator of something wrong. Here's what I'd look at:
- compression / leakdown test
- fuel pressure (should be around 40-43 psi)
- fuel injectors

valve springs will do it too broken outer big spring will work great till about 3500rpm then valves will start to float because of lack of spring pressure take valve covers off that motor and look for broken outer big springs but before that check if motors run even rpm till about 3300rpm
