Good afternoon folks,
I'm posting for my Dad who owns a 2008 Honda BF150 and has been troubleshooting and replacing parts on it for the past few months. He asked if I could help do some research and I figured this was the best place to ask!
He was able to water test it yesterday and experienced the following:
- Able to get up to 3800 rpms and that is when the engine starts losing power
- Does not stall completely
- If he stays on throttle it will surge/lose power
- When he backs off the throttle, the engine recovers and he's able to jump back on plane but issue persists at around 3800 rpms
He has replaced spark plugs, fuel lines, low pressure pump, fuel filters, water separators, spool valve, and MAP sensor. He thoroughly cleaned out the VST as well.
Any ideas or advice on what we should target next? Thanks!
