Build pics of my Aeromarine Titan 33

[OshkoshMono]

Got the Neu 1521 installed with new jacket, and 40mm rear mount. Had to do a little epoxying. Also, does my drive dog/ stinger gap look ok?

[JMSCARD]

yes sir clearance looks fine.... but what the hey are you doing with a carbon prop with that fancy setup? lol...... :)

[Chuck E Cheese]

i agree, carbon a waste on that. a general rule of thumb with no bearing is the gap should = the diameter of the shaft. i use a thrust bearing, look at how mine is set-up, the motor isnt in but you will get the idea.

you might also think of going to a .187 shaft if you have problems with it breaking. looks like you are using a .150, i know that is ok on a 1515 but worried it may be to small for bigger props on a mono... just a thought. if you run it without a liner you should be able to use the same stuffing tube, just requires a shaft and coupler.

Ha. Ya the carbon is just to figure out the prop size I need. Now with a lower RPM motor I'm really not sure what prop I'll end up running. That would just figure if I ended up breakin cables now. So a .187 would fit with no liner. Is the prop shaft the same size then? It would have to be I guess or I'd need a different stinger. Any suggestions for a prop on the 1050kv 6s setup? Hope it's not too slow. I suppose 1200 kv would have been better. Lower kv should have lots of torque for jumping out of the water eh, or just snapping cables...?

That boat is lookin nice! Those parts sure shine! So where do I get a thrust bearing? That looks like a great idea.

Looks like my stuff tube is 1/4 x .014 (6.35mm x .355mm) It says K&S stock # 131. This is my spare tube, i ordered 2 when I first started the build in case I messed the first tube up. Will that work with the .187 flex? Also I only have about 1/4 sticking out the back of the transome going into the stinger. Is that enough sticking out for linerless? I see your rice has quite a bit more tube sticking out.

Is that bushing for the stinger supposed to install from the prop end or the transom end of the stinger? I thought that it slid in from the back. I could be wrong but there is nothing to hold it from sliding out and hitting the prop.

Is your motor 5mm shaft or 8mm shaft? If it 8mm I have a thrust bearing for it.

Forescott the stinger bushing goes in from the prop side. If it does work it's way out it will hit the drive dog before the prop.

Are you supposed to tap it in gently to seat it? Since its slightly beveled at the end??

It's starts off tight. The more you use it it will loosen up a little.

Mine slides in and out like butter. It doesn't seem right.

[Rumdog]

They all do. I don't really care for it either. It really isn't an issue though. I do like how it is a slip fit in the stuffing tube though. I divides up the friction between the stub, bushing, and stuffing tube.

Darn, its 5mm. Does a thrust bearing help keep out the water that travels up the tube? My boat was taking on a decent amount of water today. Got it out for the first time with the Neu and it works great. I couldn't get the motor temps over 80 deg! The lake is a little cold, but wow what a differance a good motor and longer propshaft made. The 45mm prop works ok, but not great. I'm guessing it was running about 40 mph. Maybe 42 or 44 ish. It cavitated for a second or two then took off. I'm thinking a decent brass prop in the 48 to 50mm range will help. Not sure on 2 blade or 3 in a lower RPM setup like mine. What you guys think? 1050kv on 6s...2 blade or 3? Motor was 75 to 80 deg on the 45mm 2 blade carbon prop.

Mine too, now anyway after replacing it. The first one I pushed in and polished nice with the drive dog, not having enough gap. Ooops. That one came out hard, but the new loose one seems just fine.
