How hard and what would need to be done to convert my direct drive Caddy 15' Rivermaster to a gear reduction boat? Would the engine handle it or would I have to change engines also. Do you have to modify the rigging? How much would it cost for someone to do it? I have started saving my mad money for one of Waterthunders motors. BUT in the meantime I can buy a gear reduction unit, have it, and run for a year or so. Or is it even worth the time and trouble. Just trade it? I am very happy at how this boat handles in deep water. You can dive off the sides when the boat is stoped in deep water. Feeling safe is worth a fortune. It is what you all call a ride boat. Most of my running is in deep water. But I would love to pull up to the landing and dry load this boat, or know I can run dry if I go to Melbourne and run where I grew up. A little info from my last posts is, I changed my prop to a 0 and found out that 0 is 0 and all I did was sit there when I tried to go. I backed it up to the 1 mark and can turn 2150 rpm and no more. I changed the timing chain and bolted the hub. The timing is set at 34 deg. total but need to back off that a litthl as it is slow starting when hot. I will try a 1/2 after this week end. Don't get me wrong I love this boat but always looking for a little better.
