 home built surface drive on a tracker 1436 It isn't as smooth looking as a lot of builds I've seen but it is functional. Started with a 212cc predator engine, hill marine 9x8 SD prop, 1.63 to 1 reduction. I added a Honda gx200 bored out Carb, a billet aluminum flywheel, 18 pound valve springs, 1.3 rocker arms, 8 degree timing key and a 7/8" exhaust header. Should be putting out right at 10 HP. I adjusted the governor for more top end (which unfortunately raised my idle until I have a chance to work that problem out) so I'm turning quite alot more rpm than factory, right at 5200 out of the water. In open water I'm running 16 MPH in open water and 18 in water from about a foot and a half to 2 or 3 inches. Now if I can just get pics to upload.

Re: home built surface drive on a tracker 1436 Nothing wrong with that build. Like the use of the outboard mounting makes it simple.

Re: home built surface drive on a tracker 1436 Great job!! All you need now is to build a wooden boat so you can say you built the whole rig.

Re: home built surface drive on a tracker 1436 Thanks guys. I think it is working out good. Bigger boat will have more horses and a cleaner look.

Re: home built surface drive on a tracker 1436 post some pics of the drive assembly. I'd like to know what shaft, bearing and seal parts you used as well. I have built a long tail but not a SD Yet

Re: home built surface drive on a tracker 1436 30 inches from the back of the box, probably could be 27 but works fine.

Re: home built surface drive on a tracker 1436 The shaft housing has a bearing both fore and aft with a two bolt flange bearing with locking collar on the box itself.

Re: home built surface drive on a tracker 1436 Fyi, using the two b section belts are at least 50 percent cheaper for the setup than the cogged belt and I haven't slipped them yet except when I occasionally get too much water in the box. Does need a separate seal behind the back bearing.
