Jet Ski's are gravity feed so no fuel bubble is required to prime. Yours
(not really a jet ski) would either have a fuel pump (mechanical or
electrical) or be gravity feed. If you turn the key on and can hear a pump
running, then it is electric. If the fuel line is routed such that the
lowest point is the input to the engine, then it is gravity feed. Otherwise
it has a mechanical fuel pump that runs off the engine.
I would get a fuel bubble for an outboard and install a fitting on the
intake side that will allow me to insert the assembly into the system.
Prime and crank at home. Then remove the bubble assembly. This should get
you going. Other option would be to have the dealer install an electric
fuel pump. This will be costly and probably not worth the effort.
You might actually have a choke on the system. Can the key/ignition
assembly be pushed in any. If so, this is the choke. I also assume you are
using the cold start to increase throttle while trying to crank. Increase
throttle to wide open and then be ready to pull back once it cranks.

Your little 90hp Merc inboard is really an outboard motor, mounted
inboard.
And since it is an outboard motor, that means I know next to nothing
about
it. However, I do know that many outboard motors of that size often
have
a
sqeezeable primer bulb in the fuel line between the tank and the motor.
Not
sure if your Sea Rayder has one, but it wouldn't surprise me if it did.
I
suspect your dealer is telling you to squeeze the primer bulb to prime
the
motor with fuel. Look for a black egg-shaped rubbery bulb, probably
close
to the fuel pump. Squeeze the bulb multiple times until you start to
feel
pressure building in the bulb. Then try and start the motor.



Although Boatriger's post seems to suggest that there is no 'bulb', we'll
certainly look for one, anyway. I've read about the 'pumping' on some
info for outboards. My darling husband pointed out that this is a 120hp,
not a 90hp, but I seriously doubt that's relevant. This little boat is
basically a big, fat waverunner. ;-) Thanks so much for your time.
We really appreciate the response!
