Welcome to RIbnet
A 90HP Yam seems to be the motor of choice for the 5.4SR. HAve you still got the flooding hull on your SR? If so and you come on and off the plain allot you will find it drinks the fuel.
At one point I was using 50L an hour with my Yam 115 on the searider but I have since learned how to best use the engine to get max fuel economy and that figure has dropped a hell of allot.
Your not a million miles from me, where in Liverpool are you?
