This is showing how I’m going to be mounting my motor. I removed the original engine mounts and used those mounting holes to mount a piece of 75mm (I think off memory) box section on either side of the motor. At either end of the box section I have mounted universal rubber mounts that way the motor is supported in all 4 corners so that it can’t rock like a sea saw 🙂
With it set up this way when I sit it on the lengths of wood I have in the rear of my craft the sump sits around 25mm from the floor, which makes it hard to do an oil change in place (hehe) but the fact that the motor is lower rather than higher is a good thing as far as balance and things go.
The exhaust has been tacked in place just to see if things line up. I was going to run a separate pipe from each head into a separate muffler for each side but then thought that if both pipes join in the centre, then that’s like a balance pipe and using one muffler is half the weight of two and will sound no different, so for now that’s what I’m doing.
Here I have the muffler just sitting in place
