ever so easy to fit, a diy job, other than drilling the 4 1/2" holes in the transom, they're a wrist breaker.
You could probably get dave to fit them if you didn't want to do it yourself.
Assuming you have through the prop exhaust, if you already have through transom, then the motor has to come out, and you'll need to buy an exhaust y pipe!
