HI- I have a 2007 optimax, SN- 1b473256 115 hp. It has probably less than 25 hrs- my brother bought it new, and passed away 4 months later. After it being in a covered storage for 10 yrs, my dad wanted me to have it. thankfully, he kept it serviced, would take it in 2x year to have oil changed and have it started and run- etc, enough to keep it in reasonably decent condition. When I went to get it (in another state)- he had it shrink wrapped and I noticed bees. I came home and went to the lake and no water out of the tell tale- and I knew from experience to keep about 18" of weed eater line---and it was full of mud from those bees. It ran great- I took it out saturday and noticed that the speed--it would get up over 40mph and then slow down to just under 40. I discoverd that the throttle had come off full--- or the shifter came up a half inch- whatever you/however you wish to describe it- and pushing it back down- it would speed up- and the process would repeat itself.
I bought it (well I was with my brother) he bought it at cabellas- who don't really service boats- and I used to work at a place fixing OMC motors- mostly installing new ones- in the 1980s, fixing water pump issues and changing clutch dogs, and doing minor tune-ups (plugs,fuel pump rebuild, carb rebuild) but have little or no experience on mercury. BUT- its basically all very similar and the skills and tools in most cases are the same. I have never had issues like this- because the owner used to fix this kind of problem-I did mostly minor/routine stuff/installs.
Does anyone have any ideas? I'm sure there is an issue on the motor end OR on the control end---but I wanted to ask if anyone has seen this or have any ideas? Many times it seems these issues are all common- and occur frequently vs to one person. Thank you all-
