Proboat Zelos G 48" Cat Gas Powered!

I have two of these Zelos 48G's and two members of our club each have one.

They all run about 44mph bone stock and are a blast. A 1.4 pitch prop will get you to 45-46 mph and fixes any clutch issue. We all had to fiddle with them and run 2 or 3 tanks of gas to get them running well.

I'm sure we'll have these boats running 47-49mph as we learn to dial them in.

But even at 44-45 mph running these boats all together is such a blast. I'd like to get another so I can join my two sons and have 5 of these all running together.

Spray WD40 in the clutch housing and get needle clamps for the carb, also run the NGK CMR7H.

My one son has flipped his 3 or 4 times and it always lands prop side down and keeps running. I think these are the most fun boats on race day.

any hull cracks? what prop are you running? glad someone experienced took a chance. think I'm going to buy one. thanks

No hull cracks.

We're finding the stock (B&S) prop get's us best speeds so far, 46 mph. Still tuning, next weekend we hope to reach 47 mph, still 100% stock.

We did start running with out the canopy, seems to help. W/O the canopy we've added a 1.5" windshield at 45 deg. and wind deflector at the back of the canopy opening to prevent the parachute effect. I'll try to post pictures.

Have you guys tried running a 257 full mod carb on any of them? It may get u some more power. You can also run a copper head gasket for more compression and pick up some power there. Gas boats was my thing for years. I'm currently resurrecting my full mod express craft thunderbolt.

can you say where you set the strut to run best? needle valve settings? just bought one. going to try stock prop and prather 270. how often should I spray wd 40 into clutch housing? thanks

Low Speed needle 1 1/4
Hi Speed needle 1 3/8
Be sure to get a needle clamp, or needles moved at WOT.
Haven't even moved the strut yet, it's flush to the bracket at the top I believe.
WD40 clutch about very full tank of gas or when you lube the flex shaft. Or every time you flip the boat.
We're running 46 mph w/o the canopy on.
Sunday we'll be testing with and with out the velocity stack.

[Scratcher405]

Oh yeah, NGK spark plug in the "7" heat range (I forget the full NGK number)
Also running VP110 fuel with Yamalube 2R

just read the instructions for cable greasing. seems like alot of work. anyone come up with an easier way? appreciate your help setting this boat up. seems well made overall. one thing I don't like, though, is nylon thrust washers at the strut between drive dog and strut. have you seen significant wear of the washers? going to run sunday. have a couple props to try. also going to try larger 2 blade props with the strut set even with bottom of rear sponsons. more like a surface drive if you will. I have a zelos 48 electric, hull only which I ran with a 10s motor. torque roll was too much until i raised the strut. will let you know how I make out. thanks again.

Zippkits has a bearing to replace the nylon thrust washer between the drive dog and strut. It's actually acetal, not nylon. Just ordered a few to try out.

We got up to 48 mph today with the Zelos 48g, 100% stock.
We put the velocity stack back on and angled the prop strut about 5 degrees to raise the bow. (It used to be level with the top of the strut mount)

50 mph is within reach for sure, just need to spend time fine tuning the carb needles and prop strut.

ran the boat for about an hour. stock prop worked well. impressed with handling. one problem however, the steering servo won't center. my friend has the boat and haven't looked into it. is it waterproof? some water got in, not much, though.

Been out of the RC business for a long time but my wife is getting me a new Zelos 48G for Xmas. I've been a good boy I guess! So might have a few new questions. First one I can think of is if the boat will run about 45 minutes how long will the receiver battery last in the boat?

If I had a 48” gasser I would definitely run a large receiver pack with a castle BEC to compliment its larger fuel tank that I would install, probably tap into the existing fuel tank with a MSR fuel bottle
