I bought an old USCG boat a few years ago that came with a pair of 225's. Can't figure out how to tell year from model or serial, but here's the model/hours:
Port: BF225AK1 XXCA with ~2100 hours
Stbd: BF225AK3 XXA with ~270 hours
They have been bomber so far, but recently the older Port engine started having issues a few weeks back. It starts normal, sounds normal, but won't go over 4200 RPM. Applying additional throttle doesn't do anything, no stall or weird sounds.
A few weeks prior to this I noticed that the Port engine starting consistently burning +2 GPH than the Stbd - which was a change - as they have been almost identical matched on burn for the two years I've owned it.
Had the local Honda shop go through the engines in January this year. Replaced hi-low filters, timing belt, tstat, plugs, impeller, did valve-adjust etc. One comment on the Port engine was "VST drain screw seized - was unable to break loose". Also had them install new throttle cables back in July.
Only other maybe related change I can think of is that I accidentally ran a half-tank of E10 through it around the time (unfamiliar fuel dock - and I didn't realize marina's sold anything but e-free, by the time I realized, it was in), but that fuel has long been used up.
Checked the transom water-separators to see if any obstruction or water, they seemed fine.
I'm kind of a mechanical newbie - so go easy on me - but wondering if there's anything obvious/easy I can self-check before I make the trek back to the Honda shop. Boat is on the water and it's tricky for me to get it out - so it's not that easy for me to start tearing into engines...
Here's a piccie of the boat if it helps inspire a reply
