I have a good bit of time with one that pushes a 27 foot Stiletto Catamaran (about 1600 pounds). Good engine.. It had set up for 7 years since having been run and corrosion blossoms had blocked the cooling passages. Pulled the head and rodded out the passages and it has been doing well for a couple of years now. Electric start works fine and the alternator makes a little power to keep the battery up. Starting trick: there is no choke but there is an accelerator pump in the carb. before starting put it in forward gear and open and close the throttle 3-4 times to squirt some gasoline in the manifold.. then go to neutral and crack the throttle and hit the start button.. fires immediately. The engine (long shaft sail drive model) pushes the boat very well and uses a little less than a half gallon per hour on the average. Nice having the shift and kill and throttle controls all on the engine tiller.
I must agree I have a yamaha 1989 9.9 exf starts very every-time has been on three different boats. This motor has a lot of low rpm power the 11inch prop pushes a lot of water and can stress the typical outboard motor mount. I agree that the need to address corrosion issues, the bottom paint can set up some electrical currents that will result in damage to the motor and lower unit.
Ditto here. I have a 15 on my dink and an 8 on a small whaler. They are both the sweetest running outboards I have ever seen. Both are about 4 years old, start on the first pull every time and are remarkably quiet for 2 stroke engines. Love 'em.
Do you have a rich / lean knob? I have one on our Evinrude 9.9 1990 2 stroke. I asked this same question on the C25 Association website -- those guys really know outboard engines. Here's the link: http://www.catalina-capri-25s.org/forum/topic.asp?TOPIC_ID=23728
