All of a sudden I'm getting a poor hole shot with 1989 Mariner Mag II 150 hp engine. After I get on plane everything seems to run good. However, I noticed at WOt and fully trimmed I'm now about 200-300below what I normally run. Any idea what I can check to fix this problem. This happened while out on the lake so it is not related to any changes I made to the boat or engine setup. Before this I never had a problem.
