I am going to put a 6 cyl 90 HP 1984 Mercury on my corrytuck 16 under restoration. A few problems:
1)zero or 1 hole up, which is best?
2) which pitch on Merc alum. 3 blade prop, some say 19" consider lightweight application
3) do 1970's decal fit my engines cowlings? I think the front element is slightly different
4) in case no.3 is yes where can I get them? They will obviously say 1150 not 90
Thanks a lot to my dear American friends.....my Boston will have an American flag!

Currituck I believe.
Anticavitation plate should be at least 1-1.5" above the hull.
Prop I am not sure of but a 19 sounds like a good size being redline is 5250 on that engine. For decals look on E-bay, I see them for inline 6's frequently. Saw a nice set of early 70's blue ones for a 115 a week ago.

Andrew - Nice to hear from the Italian design community, and we appreciate your country's support!
I have a pair of Mercury 1984/1985 Mercury in-line 6 engines on my 18 Outrage (brown-yellow decals), so am familiar with your situation, and ran this same engine (115 version) on the classic 16 hull that you have. I think you can still get a new set of those 1984 decals, but I don't know if the older ones will fit.
If the engine is in good shape, the boat will perform very well, about 47 mph. I would put the engine in the third hole up, and buy a Mercury SS Laser II 20" pitch prop. You will get great performance. If you use a conventional SS prop, buy 21" pitch and install engine in 2nd hole. Don't use an aluminum prop, as it will not perform adequately with that much HP and speed.
Good luck to you.

I have a 1973 `16 Currituck and I have a 1975 85hp Johnson on it. I use an OMC Aluminum 19" on it and it flies with 1 or 2 people in it. 3 or more and it is noticably slower, that`s where a 17" would be nice, but it is usually me and my dog or me,my dog and someone else, so a 19" prop seams to do very nice :) A 90hp Mercury should be plenty of power for the older lighter `16 Hull. I personally would go 50-60hp 4-Stoker if my engine died terminally.I don`t nead speed, but fuel mileage and slow trolling and quiet is what I crave!! Jack.
