I have a 91 PS 190 with a holley carb. Is it possible to convert to a throttle body fuel injection system like the 94 PS 190 has? Can you buy a kit? How much cost?

This is the system that is most economical.

Have you installed one before? Looks like a lot of parts.

It says that system is rated to 275 HP so if you have the 285 HO motor it probably wont work. It is also calling for 15 lbs of vacuum at idle.

It is calling for a minimum of 15" of vacuum to eliminate big cams.

These are pretty simple systems. Take a close look at the parts. Mostly fasteners. It won't provide much improvement over a properly tuned carb though. Performance will be roughly the same. I have not installed one of these.

DON'T...just invest in a new carb $600 bucks, use good fuel!

We just went through 3 weeks of heck trying to bring back a HOLLY TBi system. Look on the CC site to see how many issues this system had. Finally sent it out for a rebuild. Came back and the IAC was bad. A chysler product on a holley system

Just get a new carb

Back in the day!!! 1993-1995 when I was using a CC. I had all 3 versions on the 300 HP FORD 351

A carbed one
A TBI ( It sucked the fuel) and the
PROBOSS GT-40 MPI. The most fuel effiecent and most powerful

The TBI drained my wallet...and as always a pain!

Just my 2 cents of input from experience

In 1991 MC only came with 1 engine FORD 351 240 HP 1:1 or powerslot. That year
the 1:1 failed USA Waterski boat test Powerslot passed

1992 the 285 HP HO was introduced
1993 STANDARD FUEL injection!

If you have the 1991 FORD 351. Get a new intake, and get a new carb!

My suggestion!

You could upgrade the engine with GT40 heads....That would also help!

Pretty sure '94 was std FI.

'93 was either ford carb or lt1 FI (not many though)

Right?

I think you are correct. I was looking to buy a '93 S&S and it had a 351 with a carb (285 HP I think)
