31cc ryobi engine mounts

i was given a basket full of some used wacker engines, one of which is a 31cc ryobi with a clutch that starts right up. my question is has anyone ever used one of these in a boat? if so can you show me some pictures of how you made mounts? i pretty much have the carb side figured out, my problem is the back of the engine. the next problem will be trying to get the recoil starter on the top instead of the bottom.

thanks in advance for your help guys.

Hi i built a wildthing with the 31cc engine but it didn't have a clutch,I space the back casing 1/8 with a alum brackets that i have made.
I am not able to post pics for a few day i am out of town working,but you can go on youtube and see some vids of the boat.

the youtube channel is ( hubey12 ) he is my camera man lol.

I think one of my biggest concerns is the recoil housing since these engines run upside down in the string trimmers. If you could fill me in when you have a chance on what model recoil housing to use it would be very much appreciated.

I think I figured out the recoil housing. I trimmed down one for a bolens I had sitting around I just gotta get the pull cord switched around, shouldn't be much problem.

Is this what you engine looks like ? It's a 31cc from a Bolens trimmer.I was trying to use it in a boat,but when I relized that the carb would be down and between the rails I gave up on it. I think the guy I gave it to used it on an airboat.

Yes, that's what it looks like.
