I have a 14' alumacraft flat bottom boat, I belive its close to the 1436 model, but it's probably 10 yrs old. nothing is falling apart on it, the transum is still strong. right now I have a 15hp game fisher on it but I want to put a mercury 15hp 4 stroke (111 lbs). Think the boat can hold it???

There should be a manufacturers plate on the inside of the boat.This plate will tell you what size of motor your boat is rated for..Hope this helps..

Depending on the weight and configuration of the boat...vee hull, flat bottom, etc. The 15 HP will provide faster acceleration and will provide more top speed, especially if used with the proper propeller. On the other hand, the 9.9 weighs more, but will provide better fuel economy and be slower in both acceleration and top speed. It's a trade off. If you're going to have two or three people (including yourself) in the boat, I'd go for the 15 horsepower, since when you're displacing weight, there is no substitute for horsepower. Plus, the initial cost for the 15 should be much less than the Yamaha. If you're looking for fuel economy, the Yamaha doesn't need oil-gas mixing, will go further, but slower, on a tank of gas, but is heavier. My favorite match was a Johnson 18HP on a 14 ft Aluma Craft. With two people it would literally fly and get us across Barnegat Bay to the inlet fishing grounds in no time. I'd bet the 15 would be similar, unless the aluminum boat you're talking about is a heavy one. Hope this helps some.

Maybe the question should be why do you want a four stroke when a two stroke would be cheaper and lighter. Considering the new generation motors don't require fuel mixes as they are equiped with oil injection technology. The two stroke motors are a much better option for the sort of work you are capable of doing in a flat bottom boat.

It should be OK, I not think there is a big weight difference between 2 and 4 stroke.
What you will need to do is distribute the weight more in the boat. This will require inviting me and I sit in the front with the Beer Cooler in front of me. I think it work fine then. ;-)

refer to the coastguard sticker on the boat if the boat has no coast guard sticker then it is not legal to put a motor on it and use it in public waters.

if it's only 36 across the bottom, i wouldn't do it. we have a customer that does it and the transom is only about 4" above the water. if he ever loses power it's going to swamp. BUT, it does float!

If the transom will take it.
You should be able to experience some pretty hair raising rides.

I have had bigger motors on a boat that size.
