those 20hp big block OMC motors are amazing. shows you the torque it has pushing that heavy ski around... and only 20hp and setup pretty badly. some playing w. engine height and props and it would be way faster.
Yes I agree chain drive and water off jet unit for cooling👍 However the CANAM MAVERICK BUGGYS are huge and run a belt drive trans mission grab one of them belts🤷♂️
It's a huge georaphic boats and RU-vid, you both have excellent fabrication and engineering skills please re do something like this with boats, 'story telling ' and better filming and rebuilding you will reap huge rewards!!!! Not shuttling. Your doing great, not claiming gold deserve
Great work at least your giving it a go! Love the channel.. Why don't you use water pick up off jetunit for engine cooling? Wonder if a chain drive would work? 🤔
The water feed off the jet is a great idea and I will definitely be doing that. As for the chain, chains and salt water don’t mix well at all and when the chain rusts and breaks, it will cut a hole in the bottom of the boat. Also those belts are designs to replace timing chains in high hp applications when chains start to fail. We’re building a new belt drive with a bigger belt.
Stock Holden 6 only revs to 4500rpm before the lifters pump up and the valves float. The jet unit makes max thrust at 6800rpm. The 2:1 belt drive keeps the engine rpm low and the 6 cylinder has more than enough torque
