waking up the Johnson 110 from a 2 year slumber

[gregory]

I have a 1989 Johnson 110TLCE that has been sitting in my garage for two years. When I last tried to run it it had what I thought were carb issues. I took it to a small time boat repairman and he cleaned the carbs and said it would run fine. I took it out and it did run but not fine. It idled ok and ran at full throttle well but it didn't want to make the transition from idle to full throttle. I can't recall whether it did better by very slowly accelerating or suddenly accelerating but under a normal acceleration it would die every time. At that I put the boat in the garage and got distracted for 2 years.

I confess that I did not properly winterize it though I did make sure to drain all water from the engine. It still had gas winterizer from the winter before it's last use and I hadn't put new fuel in it.

So now I have the ambition to get out on the lake again. I figure I have two problems.
1st, I've let it sit and it's probably gummed up.
2nd, is whatever was causing the acceleration problem.

For problem 1 I've ordered carb repair kits and am taking off the carbs to clean them up. New fuel filter on the way too.

My first question is what other things should I do to it to wake it from my two year neglect?

2nd question is what should I be looking at that would cause the acceleration issue?

I should add that the acceleration problem did not happen when I test ran the engine out of the water with a hose adapter to the water intake. It ran fine under those conditions. The stalling only happened when the boat was in the water. It seemed that the added load of the water on the prop made the problem show up.

Cleaning carbs and resync them may resolve it. May also need to replace water pump.
