You`ll love the 242LS great little boat.

I was in ft walton a few months back. Took a guy that came in a 28 donzi with twins for a ride in my 242. He was amazed at the ride difference. I love the 242.

And this was my boat before gm owned it. Like he said, he performed surprisingly well at LOTO.

Can you say which brand and size you had as a 4-blade? My 1991 242LS has a 7.4 and now a 3-blade vengeance 19 prop but makes 5000rpm and 52mph Thanks it would be a lot of help.
Greetings from Belgium ;-)

Mercury revolution is my preferred prop for the 242. If you are getting 5k out of a 19 I'd try a 19 revolution. May lose a few rpm and end up needing a 17 or have one worked to an 18. Wont know until you try it.

Good info on props, thanks

I pick up an old tread but I take a 4 blade revolution, now I do 5000 rpm with 3 blade 19 so take 4 blade 19?
My friend told me to put a Mirage plus 21 because he also had good results with that so yes a difficult choice then?
The props cost an awful lot here in europe, you easily pay 800€ and you can't test them. you buy one and the size isn't right you have bad luck ....

Not having the ability to try them out before purchase does make this a gamble. I have ran quite a few props on my 242. The revolution is by far the best for what I like. Handles great, bites hard and holds it. I would hate to see you spend that amount of money on a prop and be disappointed. I dont believe your engine would turn a 21 to peak rpm. If you are 5000 rpm with a 19 vengeance, I would try a 19 revolution before I tried a 21 mirage. The mirage is a faster prop on the top end, but the low end and cruise (in my experience) was better with the revolution. Pitching up from 19 to 21 I would expect you'll loose roughly 400 rpm at wide open throttle.

My Rev 4 also holds the bow muck better (less bow porpoise) and much less prop steer thrust on the steering wheel, it tries to track straighter than with the Bravo or Mirage props.
And I know a guy that just gave a like new 19 Rev 4 away.

Here in Belgium the props are really expensive compared to USA.
Now he has a max speed of 48mph and my son would like to go faster, 400 rpm lower at full throttle is 4600rpm than I have just the max rpm for this engine.
Here in the Netherlands is some guy one for sale ut is a revolution 20...
