Re: MAS 540 to Fuel injection

Thanks for the reply, I'll give him a shout. Did you have a problem with dieseling prior to swapping over?

MAS 540 to Fuel injection

I've got a new MAS 540 that Id like to swap over to fuel injection. Any idea on what the cost would be? What kit to go with?

Re: Dialing in new boat..

Update- I got the 4 blade NGR on the boat and it runs great. Max rpm at the 2 mark is around 5200-5300. I definitely think this is a much better prop for my set-up. Runs a lot quieter and seems to push dry ground better. I would've liked to try the JX with the 2.5 but I'm happy with the way the boat...

Re: Dialing in new boat..

Swamphunter I agree that I think he would be better served with the 2.5 ratio and then keep the 4 blade JX. It makes sense to me that it didn't do good/best when he was turning 5400 because he didn't have enough blade angle/pitch to suit the blade. What is crazy is when he pitched them to only turn...

Re: Dialing in new boat..

It sort of makes for more questions. I prefer to run an extra blade on a gear drive boat rather than run a heavy pitched prop. That said every series of blade is different and some may work with heavy pitch better. That engine is what Blackwater runs and it should be a beast. Jason runs a tour boat...

Re: Dialing in new boat..

I'm kind of puzzled with this choice of blade on a 18ft X 8ft powered by a 540 MAS Was the JX selection something you wanted or did someone from Sensenich feel they were your best option ? When I first heard of the proto type blades being tested was around the time I was buying my S blades and we w...

Re: Dialing in new boat..

Dropped the boat off yesterday and gonna have them put the ngr on it so I can compare the two. Everything I've read says that the jx should be a better ground runner than the ngr. I guess we'll see.

Re: Dialing in new boat..

The boat runs dry. I went from a 16' with a 383, 2.3:1, 3 blade NGR to a 18'. Same hull just 2' bigger. Deep water cruise & top end are better than the previous set up but dry ground running seems about the same if not a little less. Only going 2' foot bigger and adding 300 plus hp, I was expecting ...

Re: Dialing in new boat..

The builder made a couple of adjustments. He started by adding a little pitch and we were able to break free at 3200rpm, in the field next to his shop. He then decreased pitch and tried that, of course it took more rpm to start moving so we went the other way with it again. This time he said he adde...

Re: Dialing in new boat..

Well I added some pitch and it does seem to have a little (very little) more push but I'm choked down to 4700 max rpm. I'm not sure if I should of went with the 3 blade so I could have both, the pitch and the prop speed. I was originally going to go with the 4 blade NGR and switched to the JX at the...

Dialing in new boat..

Running a 18x8 with a mas 540 carbed, 2.3 to 1 pushing a 4 blade JX series. Currently Im turning 5400 rpm which according to the dyno sheet is 726.3 CHp and 706.4 Clb-ft. At 4900rpm it shows 676 CHp and 724.5 Clb-ft. My question is, should I put a little more pitch in it to get around 4900 max rpm? ...
