I purchased a used 2010 G3 V167c with a 50hp Yamaha 4-stroke in the spring. It had around 100 hours on it when I bought it. As far as I know, it was regularly serviced at the dealer where I purchased it from, and it was running very well for the first month I used it (which was June). It accelerated well, planed very quickly and had a top speed of 33-34 mph.
Then about 2-3 weeks ago, I noticed that it didn't accelerate as well, took a little longer to plane, and now has a top speed of about 29-30 mph. It never stalls and I never have trouble starting it or restarting it. The only noticeable things are the lack of acceleration and speed.
I treat the gas I put in with Sea Foam (about 3 oz per 5 gallons), which I stopped doing when I first noticed the problem. I thought the Sea Foam treatment might have been causing a problem, but after reading more, I suspect it's simply water in my fuel. I haven't confirmed that yet, but I will this weekend (by pumping out a small amount of fuel into a clear container to examine it).
So I'm thinking that I should install a water/fuel separator, but I'm wondering if that will actually solve the problem. What do you think? If I was having trouble starting the engine or if it was stalling, I'd certainly take it to a mechanic first. But considering my problem appears to be minor at this point, would installing the separator possibly solve the problem (assuming it's water in the fuel)? Just looking for some opinions on this. Thanks.
