Mayby compresson and leakdown test on that tomorrow |
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 |
145psi all over plugs looks rich. Injektors was sent away 2 month ago. Only checkd fuel pressure at idle. Was 43 psi at idle. |
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

Screwed up props will mess with it also. Have them checked. May not be them but the easiest and cheap to have them looked at. |
Have the same boat. Bet your engines are getting tired. My speed is down too along with compression. Should check yours.
|
I have 145psi all over. Going to test anorher set of props this or next week. If that doesn’t make any difference. It might be the engines. |
145 psi sounds a little low - my 525s with 200 hours were about 160 cold.
