So the boat ran great after de winterizing checking engine on land running etc and launching it 3/4 weeks ago. Speed and power were normal and was able to get on plane coming from launch ramp back to dock slip. 1 week after launch I went for a second ride with 2 friends and we all noticed the power was extremely different than last season, I then realized we were going 10-15mph full throttle (WOT) and not able to get on plane. Almost felt like we were crawling but the RPMs were at 3900/4000 which I thought was odd so we Bring the boat back in. 1 week after that I go again and she starts right up at the dock runs for 5-10min No stalling at dock and head out. we’re out of the harbor but power still low , anchor Turn off then leaving fires right up and bring her back in low power.
Now third trip out since putting her in I start her at the dock and she is idiling at 2000-2500rpm and seems jerky, stahls out after 5 min. Primer ball check - I restart her and she’s fine so we are out on the water anchor and hang. Go to start - it cranks but won’t start. Prime , start, nothing, wait 5 minutes she starts stalls. Wait another 5 starts and I give throttle right away and we are able to get heading back into the docks
I changed the spark plugs as my first thought then fuel filter was my next, I noticed a nipple out of the fuel filter side was popped off a plug so I popped it back in and started the engine. Runs then puts out after 5 minutes. Idle still seems high at 2-2500rpm in neutral
Any ideas what the problem could be? Bought this boat last August and have only taken her out 15-20 times max and not seen any trips longer than a mile or so out of the harbor
