[QUOTE="LarryMc, post: 432009, member: 13895"] I've decided to stop wasting time and money trying to improve my Mercury 4S 40 Jet's performance with my boat to a point where I'm satisfied with it and am going back to a 2S. I'm planning to buy a used 75-90 HP motor and converting it to a jet since the new 4S factory jets in anything bigger than a 40 HP are so expensive, not to mention heavy. What I would like to do is find a Yamaha 90 2S since they are about the lightest motor going in that size. The problem with that is my boat has Mercury controls and I'm not sure I can do the electrical work needed to swap out the controls to Yamaha controls. I can do all the mechanical parts with no problem since I've done it before several times. The boat is a center console and has binnacle controls and a separate start switch which makes it even more complicated. Of course, the easy way to go would be to just find a used Mercury 2S 90 which I might end up doing if I can't figure it out. I've already been quoted a price of over $1000 for parts and labor just for installing and wiring up a Yamaha control to my boat. :shock: Anyone here done a control swap similar to what I'm talking about? Any advice would be appreciated. [/QUOTE]
