Good Afternoon All,

I own a 2001 Horizon 200 5.7 Merc. The boat has around 120 hours. I was out on the lake this weekend and this was the first time I had it in the water and docked. I had the boat out multiple times no issues at all. I was out on thursday with 6 people plus towing one wakeboarder. Had plenty of power and planed off like normal. I docked the boat for the night came back to the boat and went back out in the lake and all of a sudden I couldnt get on plane. I confirmed my trim was the entire way down at the time as well. It was like I was not getting the power I needed to do anything. The strange thing was after a while the boat came to plane and the RPM's rose like normally to around 4200. The boat does have a hydrofoil on the outdrive. I spoke with my tech and he is saying its the trim on the outdrive but the outdrive is going the entire way down to the normal marks. The motor did struggle to start twice this weekend but overall no knocking or misses.

Here is what I tried:

1) Thought maybe bad gas - Replaced gas with a known good fuel source.
2) Replaced the Fuel filter as well
3) Confirmed the outdrive was completely down.


Any Help would be great
