I have just purchased a 1991 Maristar. It has a Ford 351 engine. The previous owner states that he believes it is a 240HP. How many versions of the 351 were there for this boat and how do I tell which one I have?

That's about right. I believe the manual quotes 250hp with a top speed unloaded of 47. Don't quote me.

240 HP

The HO 285 HP Ford 351 Motor did not come out till 1992 for use in a MasterCraft

Why is that not what you wanted to hear? Remember that your tranny should be a 1.5:1 which will help with your hole shot. I think the 454 was the other optional engine for that year and would come with a 1:1 ratio tranny.

I have the 454. Good motor, but a very thirsty one. You and the guy at the gas dock are the only ones who will know how big your motor is. If the 240hp pulls you well, enjoy. I'll be the guy filling up for the second time that day.

The proper answer is 240HP.

Just for the record is has a 1:1 transmission as I looked at the nameplate on the transmission berore I bought it. It is turning a 13 x 13 3 blade prop. It has enough "get out of the hole power" for me.

I grew up when Correct Craft Mustangs and the like were king. 260 Cubic inches was the normal. We thought that was enormous power as opposed skiing behind a 50HP outboard.

This is my third inboard that I have owned. The first one had the 240 HP 351 Ford, 1:1 tranny turning a 13x13 prop. The second was a 290 HP 351 Ford, reduced ratio tranny. The difference in fuel usage was staggering. Admitedly the second was a larger boat but the weight to HP ratio was about the same.

I'll give up some out of the hole performance for better fuel economy. Don't get me wrong I love power. I raced hydroplanes for 3 years.

I hate to burst your bubble here

The Powerslot 1.5 to 1 was a approx a $1500 upgrade. A powerslot tranny was NOT a STANDARD option

In 1991 the 1:1 240 HP PS 190 did not pass the AWSA acceleration test. The Power slot did. In 1992 when the HO 285 Came out both the 1:1 and the powerslot passed.

Many hulls in the late 80s and early 90s all came w/ a POWERSLOT tag by the throttle handle. This was a common misconception that the boats where SLOTS because of that sticker. There was one on my first 1988 PS 190. I knew I was purchasing a 1:1. MC probably just labeled all PS 190s with that sticker.

The 454 also came as a !:1 and a powerslot
