Newtauk, 17',1988 /. 1999 90hp Evinrude, have in hand son's 18hp short shaft 18", weight about 85#, can I use this as a kicker, or do I need to sell it and get a 9.9 long shaft 20" ???? On hand no money needed, also has whale tail. Run good and a clean motor. What ya think. Mike

Given the weight of that engine I am assuming it's an older engine. If so, I don't know how they measure the shaft length. On my Montauk anything shorter than 20" wouldn't work, but that's not to say a bracket wouldn't allow it to go down a few inches more. Keep in mind weigh is a big factor on these boats. I would not suggest anything heaver than a new 9.9 4 stroke. Also, many people use lesser hp on these boats. I replaced my 2 stroke mercury 8hp with a 4 stroke 9.9. The new motor doesn't push it any faster than the 8hp and the additional weigh is noticed.
