Several mos ago I asked for some suggestions. I want to thank the gents who suggested replacing the low-pressure fuel pumps. Took the boat out for a hop, runs great. No stalling, no towering clouds of smoke, better top end, and shorter cranking time until the engine starts. Fairly simple job. Thanks again.

How many hours? About 1 hour, and most of that was tied up trying to get the little cable ties into tight spaces and out again. Each pump has only two 10 mm bolts, piece of cake. I used a 1/4" ratchet set with universal sockets, got me right into the tight spaces. I did have to unbolt the VST and move it out of the way, but I didn't have to actually remove it. Let a dealer do it? Probably looking at $300 plus.

I had about 200 hours on the engine. But this number is misleading. I bought the boat in 2008 when it was 10 years old. It had 100 hours on the engine then. The previoius owner was a Wall Streeter who wasn't allowed to take vacations and the boat just sat. According to the marina, who acted as broker when I bought the boat, the owner would just take the boat for a short ride 2 or 3 times per year for 10 years. The point is this. It's not the hours in my case, it was that over those 10 years, the rubber diaphragm in the low-pressure pumps dried out and didn't perform as intended. Someone on this site suggested that it should be done every 6 years or so, just as a matter of preventive maintenance. The cost of doing the job is cheap in comparison to most things you have to do to a boat. If your boat has a few years on her, go ahead and do it. Suggestions - call Andy at SIM, and get yourself a 1/4" drive socket set with universal sockets - it makes it really easy. The old story is if you want to play, you have to pay, and this is a small price to pay for a lot of piece of mind.

I have a 99' 225 that has had a similar life. I think the high pressure fuel pump was replaced by the previous owner a few years back not the low pressure. I need to check the paperwork on it. Was the ethanol to blame or was it simply age?
Age, for sure. I went out a few weeks ago after replacing the LP pumps and she ran well. Did alot of stuff - re-set the trim tab, plugs, filters, definitely a happy engine. And I was running last November's fuel in mid-March. I swear by PRI-G and Startron in the tank together to keep the E10 from breaking down for a long time.

Did you use the correct cable ties for all those hose connections?? (3-pumps X 2 = 6-4" ties) They're not the same as the ones you get from Home Depot. They're radiused at the clamp. If not you don't have a tight seal.
