should'nt i be seeing water stream and water pressure out my ox66 when I hook

should'nt i be seeing water stream and water pressure out my ox66 when I hook it up to the ear muffs or do i have to wait for the engine to warm up before it starts running water through the cooling system. Put a new water pressure gauge on today wasn't getting any pressure or stream out the hole didn't let it run more than 30 secs thought I should ask first, i put air hose from the motor to the gauge and it's showing it works ok no blockage, thanks

If its like a Merc it will take a while until the thermostats open.

another thing, make sure you have sufficient water pressure form the hose.

I tried the same thing and got an overheat alarm. Shut it down and took it to the dealer (motor had less then 30 min run time on it - aqll by them).

they tested it and it was fine. took it back home, same thing. Took it to the local ramp and dunked it in, it ran fine.

When I got back home and was hooking it back up, as I turned on the hose, I heard a hissing noise. My pipe had split just under the house, and wasn't giving it enough flow/pressure. Fixed the pipe, and it ran fine.

maybe no water at the back, but should have some pressure on the gauge

Dad has a yamaha and we have put it on ear muffs before and saw no water coming out. Hooked it to the flush valve and worked fine. I have 2 different muffs, duel and single. The single works better imo. Dad has the duel muffs, that might be the problem.

My first yamaha so trying to get used to it and learn it. Had the boat a month and still haven't had it out, vacations and lately all the freakin rain and flooding. Getting the new batteries today and going to take her out. Thanks. for the replies...

I've seen a lot of people post they have little or no pressure on the hose. My 200HPDI will "pee" and I get pressure when on the hose & muffs at the house. The pressure is lower than when on the lake, but I do get fairly decent pressure on the gauge.

I had on round set of muffs that apparently did not seal well on the rectangular water intake of my lower unit. I've since bought a heavy duty set of muffs with rectangular cups that fit better and I did notice the pressue is better.

Had the same problem with v-max 225, bought one of these and works great, also does a good job with washing the dog

Bet that works slick...and makes it a lot more quiet I'm sure too.

I have a 200 VMax and water starts coming out the "pee" hole within a second or two after starting it using the muffs.
