2009 Honda BF200. This one is kicking my A$$. Just want to start with any help is very much appreciated! So…. Last season boat ran / started great all year until the last start up / trip to take the boat out of the water for the year. My port had a hard time starting – real hard. It would crank crank crank, and sputter here and there, but got it running. It ran great idol up to WOT and everywhere in between. Week or two later went to start it on the trailer, and same thing crank crank. Anyway, I found if I turn it off soon as it starts running smooth and restart, it starts perfect. Also doesn’t have to be hot. Once I fight and get it started, it runs real ruff and sometimes even stalls. This only happens for about 20-30 seconds, and it will smooth out and you could balance a wineglass on it.
Few things to note -No codes, Compression was good, Drained the VST twice - seemed full. Held the drain hose up and could see the level. Fuel was 100% clean both times. HP and LP filters replaced, Fuel pressure key on 42PSI, while cranking seems to go to 47PSI, if it doesn’t start seems to drop back to 42PSI, key off after engine running it’s about 30PSI, and Key on for say 5-8 seconds, then key off (without being started) stays at about 42PSI. Holds 42PSI for a good beer or two, come back next day it is at about 5PSI. (Done this check twice). Seems reasonable? Turn the key back on it goes back up to 42PSI.
PSI look normal? I almost feel like if it stayed at the 42PSI it would solve the problem, but soon as you turn the key on, it has no problem going up, maybe air instead of fuel in there? VST is full?
My gut is telling me it has to be a fuel issue? Had to swap parts, but yeah, I’m getting frustrated. I have its matching brother right next to it. Even swapped the ECM, Main relay, and temp sensor. Unless anyone can think of something I should try?
Both engines only have about 215 hours. Huge Honda fan, but first outboards and they seem to be the worst engines I have ever owned. Guessing the guy prior didn’t take care of them or just because it was sitting because of the low hours. Just got done pulling the power head off the other one for crank and oil pump seals, that one fires right up. Anyway, thanks so much for reading this, if anyone has advise, I want to thank you in advance!
