what brp site are you referring to. brp.com? if so, where do i go from there. gary

Here's an easier route ... go to:

www.shop.evinrude.com


Click the link for "Parts" and then go to you year/hp for you engine. You can look the parts up for Johnsons too. Just go to the top of the tree and highlight where is says Evinrude & that will then give you the choice to select Johnson.

This post is from a little while back but I did want to comment. I did this exact crab swap on my 1976 Evinrude 9.9. Everything works great. It's funny how much difference 5 hp makes I bought the carb used on ebay and some other parts I needed including the motor cover that had the "15" stickers on it. The best info I found on my motor was at this website

http://www.sschapterpsa.com/ramblings/Johnson%209.9_15.htm

By far the best source for our little motors out there. It covers the carb swap in detail.

i also have a 76 9.9 rude and have the original carb for it. the thought of upgrading has always been in my mind , but what i have runs too good so i am going to hold off on that one. i also have 76 johnson 85 and was told there was a carb upgrade for it too "maybe a 115?" i dont know but i am sure there is more to it than a set of carbs.

To Krogie: The 1976 85HP had a bore of 3-3/8 and displacement of 92.6 cu. in.

The 1976 115 had a bore of 3-1/2 and displacement of 99.6 cu. in.

Porting was different as well.

Using the larger carburetors will definitely increase your fuel consumption, though.
