There is auto trim systems available for trim tabs. I believe they use
regular mercury switches. It is a bit expensive. I'm not sure that a
autotrim system for i/o's would generate much interest. Bigger boats tend
to be inboards and can only be trimmed via tabs. Most i/o's just take off
fully trimmed down to get on plane and then trim to slightly up for maximum
bow lift. Or slightly down for rougher water.

What are the prices of Autotrim,and what technology does it use ? If
somebody knows ... Im thinking of designing a system that trims your
engine
for best performance, but im not sure what would be the correct price and
would there be anybody interested in buying it ... It should save
gasoline,
give you the highest available speed and eliminate wave shock best that
can
be done ... So any available info on the market state would really be nice
...
Thank you
