Phil I'll take that fat 40 pipe

Yep , and I'm ok with changing them redundantly ahead of time This one had little time on it and is the only bearing I actually ever had " go bad".in these engines since they came out whatever year that was . SKF installed now and logged .

OK so I'm not going to employ full compliment bearings due to convenience time and cost . How often do you run the bearings that last forever ?

The bearings come pre packed . I have never blown the grease out and cleaned them assuming brand new from the factory will be good . Now the water we run in is filled with all kinds of funk so who knows what goes through them . The Voodoo water has suspended mud particles in it but what can you...

Well we are going to do a well documented test on the SKF beginning next week at Sowega., followed by Twin Shootout in Brandon in March then maybe Atlanta .

I change bearings every3 -4 (races) . Sometimes the bearings look and feel good but if you look at them magnified under good light I have seen the beginning of surface degradation on some of the balls .

Yeah I love these engines and will replace bearings every 3 outings as necessary. This may be a combination problem as well . After every race I remove engines and remove the intake housing and dump all the needles and hand out the engines so I'm not sure what more I can do except add oil and...

Interested in a set of prints ! Lmk cost !

Using what minimal.magnification I have it appears to be one in this bearing . I think it's the quality of the bearings or corrosion.

Don't think it's heat as not burning plugs , not even close

Lol all high.performance bearings including the original have the polymide or plastic retainers .

Std Technology fuel , Klotz techniplate and castor .

I have been experiencing a type of bearing failure that's called spalling. There are different types of this condition caused by different circumstances . The VAC 91 is a notorious bearing consumer if you run the hell out of them like I and others do . The bearings I have been using for the...

Complete yes , I was more commenting on the boat minus pipe , engine , prop like Mike's boat is setup .

You will need a thicker., flatter surface to set it up on though Tim !!😂

Still going to have $500 in the boat with radio paint ,hardware and a tank . Is what it is as they say !😁

You can get in cheap but just not at the top of the food chain ! Go look at what ready to run toy electric boats run now . If you raced 1/8 scale buggies you had thousands involved . Anyway Mike's boat can win anywhere with a stock 91 and some good props . Props are everything for speed .

Well this is it . If you stand back a ways the pinholes don't look like acne !!!🤣🤣 Time to assemble and go racing!!

For sale ?🤣🤣🤣🤣🤣🤣
