1988 SunToon 20' Pontoon- Maximum Horespower?

[jamboater12]

Just bought a lakehouse and it came with a 1988 SunToon Pontoon boat and I cannot find the maximum horsepower allotted for the model. I have tried to search websites and am not having any luck. Any help regarding the maximum HP the manufacturer suggests on this boat would be really appreciated. Thanks in advanced!

Shoud be a placard near the helm. If not and if you continue to draw blanks, a very good educated guess would be 90 hp.

Yeah- I looked and couldn't find a placard. I thought there should be one there- this is my first goround with Pontoon boats!

Just curious why you are asking. Does your boat not have a motor or are you looking to upgrade already?

And welcome to the forum. Lots of great guys and info here.

Maximum HP rating is 60 HP for the JC Suntoon. Probably has 19" or 21" tubes. Hope this helps..

My '88 Lavigne was rated at 75 hp and had 21" toons.

Thanks for everyone's help! The pontoon boat has been sitting for about three years (it was winterized however) and it's got a 48 HP Johnson motor on it. I was hoping to get a headstart on my research just in case it doesn't work. We close on the 18th and will find out then! For the curious, I contacted JC pontoons and they said that the max hp on it is 70. Heres to hoping I don't have to go in search of a new motor!!

Those motors were bullet proof if they were properly maintained.

That's what I've heard. I'll keep you updated when I try to take it out...any suggestions on increasing my likelihood of avoiding problems?

Got the boat out and she started up on the first try after 3+ years of just sitting- guess those motors are bulletproof!

In case you haven't done so, I recommend that you change the lower unit grease, the water pump, and the fuel filter.
