I use the 25 Mirage plus and it works really good on Baja's with deep drives. I had extra cupping put on mine for more bow lift. Once I get through the 55 to 58 MPH zone my bounce is gone. I just upgraded my cam over the winter, I should be running 500HP or better. I am going to try top end runs this weekend. Check the Swap Shop I think I saw one listed.

there is a LH mirage plus 25 on ebay that is looking like it might sell cheap. can i reverse the rotation of my drive? and is that good for it?

I would just find the correct prop.

Fixxxer22 05-21-2009 11:20 AM

ok, so RH it is... ill find one im sure of it. someone offered me a labbed one but im afraid of dinging it up on the beach and in the canal.

Mine is lab finshed, I would buy it if it had the right price. If it does not come with the solid hub kit with the brass insert you will need to get one. The plastic one will spin out. It cost me about $300 just for lab & extra cupping. I gained 1.5 MPH and allowed more trim without blowing out the prop. I ran it for 5 years without any dings running on rivers. They do not take off enough metal to weaken the prop. If you hit a rock it will damage it no mater what. Small stick or debris should be fine.

It depends... some single engine boats like the prop turning in the opposite rotation of the engine and they tend to "lean" due to torque load while others actually pick up speed having left hand rotation. It all depends and I'd check with Baja or other members who ran it both ways.

I ran a Velocity last year and it didn't like left hand rotation while other members stated theirs ran better, go figure.:grinser010:

Fixxxer22 05-21-2009 04:13 PM

dosent running lh put pressure places it was not before. the drive has 300 hours on it at rh rotation. so would it be bad to reverse it?

Panther 05-21-2009 07:52 PM

there's lots of schools of though on that... I've done both.

Some feel it makes it last longer because now you're wearing the back sides of the gears while others feel the shafts and gears are worn in a certain direction and if you reverse the rotation it can break easier.

Flip a coin dude!! lol :)

Fixxxer22 05-21-2009 08:22 PM

how hard is it to reverse the drive and make the controls the same? because i could pick this prop up cheap.

blue thunder 05-22-2009 06:48 AM

It's easy, you do it in the shifter at the helm. I believe it would be good for a drive to run opposite periodically for the reasons panther said. Before you actually change the shifter you can try the opposite rotation prop by running the boat in reverse. Its a bit of a mind game docking but with a single it should not be too hard.
