[QUOTE="shuether, post: 458599, member: 24107"] So I've got a 1993 20hp Johnson and I've come across a jet leg I should be able to pickup for under $500CAD, depending on condition. My current boat is a 14' Mirrocraft that does excellent with the 20hp prop, handles 2-4 people with only 4kmh diff in top speed. This boat also did really well with a 70's Chrysler 15hp(~10hp when compared to the Johnson) with two people and gear. I've been wanting to get an outboard jet for a while to make it easier to explore some of the rivers near a friends place in BC that I visit every summer. I know the smaller jets are often frowned upon because of the 30% performance tax doesn't leave much power at the jet. My question being this: is it worth messing with this jet leg? Or would I be better off to look at a 30+ jet down the road? Best I've seen is $3000-4000 for anything decent in my area. Also anything to watchout for when I go look at the jet leg? At this point I'm thinking its worth a try. If it feels under powered on the 20, I can do the carb/intake off a 30 and get a little more out of it. [/QUOTE]
