I have a 2010 Honda BF225, hard to start since I bought it. I purchased it with 260 hours it currently has 290 hours on it. Prime the bulb, turn the key, wait for the high pressure pump to pressurize, 3 seconds on each crank, it normally stumbles to life on the 4th crank sometimes 5,6,7 tries. If I shut it off and IMEDIATELY restart it, it will start and I can do that as many times as I want but if I wait a bit and try to start it it will not start on the first or second try. It rarely ROARS to life most of the time it just stumbles to life. It also occasionally will surge when cruising around 3k RPM I can feel the boat surge and watch the rpm gauge fluctuate about 200rpm.
I did have the engine die once it got on plane twice after letting it sit in the water off for 30 mins. I replaced the anti drain back valve on the fuel tank and it has not done that since, seems to hold prime better as well. Just drove it 40 miles offshore to the Gulf Stream.
Parts replaced/work performed:
Inspected fuel pickup in tank
Anti drain back valve
Fuel water separating filter in hull
Checked/Tightened all fuel hose clamps/connections
High and low fuel filters
Removed, cleaned, resealed and adjusted float in VST with all new oem orings and screw
Watched the low pressure pump move fuel into a container, removed pump and plunger moves without issue but with some force
Removed fuel rail and pressurized high pressure pump to look for leaks on the injector nozzles
Vacuum tank (was busted)
6 OEM NGK spark plugs
Both thermostats
Oil and filter
Water pump kit
Replaced and adjusted throttle cables
Compression is 190+ on all 6 cyl
Injector resistance, and fuel bypass solenoid resistance is within spec
