mercury or evinrude? or?

[mercrude]

I have a 1981 rinker bow rider with a 70 hp ob that has no compresion in top cylinder Instead of rebuilding this motor I am thinking of changing it out the mercury looks realy hard to work on verses an evinrude If I put an evinrude on this boat what all would I have to change I would also like to upgrade to a 90 hp with power trim and tilt

Well mercrude, there are several things to take into consideration. What is the year of your OB now?<br />What kind is it? Mercury, Evinrude?<br />The best bet would be to change the control box for sure.<br />It will have a harness that will have all of the wires for the new motor.<br />That way you won't have to run any new wires.<br />If your present motor does not have T/T, then you would most likely have to change the control box.<br />I'm sure someone else will jump in here so I will shut up.
