I have a Miller flat bottom V-drive boat. I have had it for quite some time and have kept it pretty much stock. I am in the middle of over hauling the entire boat pretty much: seats, tanks, motor, drive train, ect..... Anyways to my point, I have had a hard time finding good tech help out there so I can it done the right way. I'm pretty much looking for more power and speed, but not sure how to go about the drive train, transmission, prop selection. Any help to get me going in the right direction would be aprieciated greatly.
Matt, in my opinion the two hardest things to do to get more speed and performance are the first things to do. One major issue is the bottom of the boat. You have to make sure the bottom of the boat is solid first, then flip in up side down and do bottom work. That consists of checking to make sure there are no dips or hooks in the bottom. If the bottom shape is bad, no power in the world will overcome that issue. In fact, it will just make it worse and increasingly unsafe. The second is to make sure the strut is set at the right position and at the right angle. (being that I don't know your boat I can not give a good answer to where that might be). Most old ski boats had prop angles in the 9*-11* angles. Most of the "hot rod" or race boats are anywhere from 8*-7*. Last but not least is engine placement for the power you are making. Many ski boats had the engine back as far as it would go to make more room for passengers where hot rods often like the engine between 30-36 inches from the transom.
Now, I would first get these current measurements as some on the board will be able to give you some direction. Also, look in the hull repair section and see how others fixed the bottoms of their boats. That will give you an idea of what you are in for. I will be in the same boat as you one of these days as I plan on redoing our families old Hallett. I have a little experience so I know what I am in for. Keep asking questions and make sure to answer questions of those who are trying to help you.
great feed back. I was hoping just to do some mechanical work because that's what I'm good at. The bottom of the boat now concerns me because that is way out of my league. I will have to have that looked at. I have been concerned about that latley with the boat porpoising more than I feel it should. As for the engine, it is pushed all the way back. I'm not so much looking to make this boat a top speed race boat, just want a little more out of the hole power. Thanks again for all the info and I will defiantly look into these areas.
I noticed you started 2 of these threads and I responded to the other one.
