The "GT40" was the multiport EFI PCM HO 351w and was always rated at 310hp (it was available 95-02). Its not to be confused with the carb and TBI versions of the HO 351w (which had GT40 heads), which were rated anywhere from 285 to "300+".

Thanks, for the help. Looking at a 98 Ski open bow, GT40 was not sure of the HP.

New here. Looking at my first boat and am trying to do my homework before diving into a purchase.

What is the general feeling of the carb'd 351 engines that came in the late 90's boats? Do they have any pros or cons over the GT40 power plant?

Socially Distorted,

The GT-40 in my opinion and of most was a great poweplant! It is still sought after today. Much, much better than the carbed motors that recently proceeded it. They are a very strong motor. If I was going to by another older boat that would be the first feature I would look for. Also, welcome to the sight and if you get a chance update your profile witha name and location.

The GT40 was a great motor- not sure Id say it was "much better" than the carb'd 351w's that preceeded it though. Im not a huge fan of the Protec ignition system, but otherwise the carb'd engines were very good as well.

The carb'd 351w's of the late 90's should be bulletproof. They'll be down a few hp to the GT40 and wont start as nice as multiport EFI, but they're a bit simpler and perform great. Protec was gone by then, so no issues there. If you find the right boat with a carb'd engine, Id jump on it.
