Oil (mobil 1 vs marine oil ) opinion

maybe that is one of the reasons they come apart from time to time.
they do run 2 separate ignition systems to try to keep it all lit up

That must be one hellava E-ticket ride. Ever listen to the drivers when they interview them after a 4 second run down the track? They are huffing and puffing like they just ran a three minute mile. Must be all of the adrenaline flowing.

I am waiting for someone to come up with a hidden computerized throttle. It will sense when the last yellow light illuminates and automatically apply the throttle. For consistent reaction times. Say .002 each and every time. Then NHRA will get suspicious and investigate why one driver can leave so fast and so consistently every time.

I think Yamaha wants a 10-30 or 40 depending where your located .

they would just need to screw up some of the less important races maybe to make it look good

What are they up to now? 10,000 hp?

From what I've read Diesel oil is good for boat engines for the reason you state, constant RPM which can cause sheer. Diesel has stuff that prevents this since many run at constant speed like boats. Since these are 2003 motors FCW spec wasn't out yet. I would have felt better with 15w40 but can't find the full synth with it. Again from what I've read the 5w should be fine. Bit more viscosity enhancers..

I would have to check first if a 5w oil is recommended by Yamaha.
then I would look for the FCW label.

wanna make an automotive tech get a funny look on his face?
go tell him that after about 15min at 5500 RPM the motor develops a miss.

most auto techs have never seen 5500 for over 60 seconds.

it is called DUTY cycle.
the outboard is MUCH different than an auto.

Transmission problem. Stuck in first gear

[99yam40]

never met anyone dumb enough to drive a vehicle down the street at that RPM stuck in low gear.
Are there some out there?
