Hey whats going on, My name is Andrew and I am new to this forum. I found you guys through reading an article In Offshore, A northeast region boating magazine. I just wanted to say I am glad I have found a forum with other loyal Seacraft Owners. I love my hull and its design. This is my first boat, and sure when I get my captains license, I will be purchasing a 23 foot Seacraft. I have had the boat boat in 6-7 foot seas and was damn proud of how she handled. I love the hull very much, unfortunately my 2000 Yamaha 130hp is turning into be a love hate relationship.

I was out fishing the MiddleGrounds off of Marthas Vineyard when I went to make another drift, and punched the throttle. The boat took off and then all of a sudden bogged down and sputtered to its death. The engine wouldnt start again. I pulled the cover off changed the spark plugs. (all fouled) and it started but ran shitty back to the dock.

I bought the boat about a year ago and this was my 2nd time using it. Turned out it had bad gas in it. I drained the tank, changed all fuel filters, all fuel lines, and cleaned out the carbeurators.

This was not the problem. Still dint run right. I ran a compression test on all of the cylinders cold, and I was pushing 125psi out of all of the cylinders.

One cylinder is not firing and gets weak spark, plus the boat does not rev up fast. It bogs itself out. This is the kicker also. When the choke is turned off, it runs like crap, but when I have the boat half choked, it runs like a dream on the 3 cylinders.

So my Question to you guys is, what the hell is going on. I cannot figure it out for the life of me. If all the coils are ok, why isnt one cylinder isnt firing, and what could be causing my bad fuel/oil/air mixture. I am baffled.

Also I want to do the repairs myself. For 2 reasons, I am piss poor. I took a huge chance buying this boat, because my life dream is to be a charter captain and commercial fisherman.

The second reason is that I own the boat and I should learn as much about the engine as possible.

Any ideas would be appreciated.

Thanks
