    Hi there,
    Quick question. Just seeing if anybody knows how to adjust the stiffness on my throttle as it backs off slowly while on plane so I have to keep my hand on it all the time. It's a 1989 Sea Ray 345 with twin mercruiser 454's with the generic separate throttle and shift.
    Thanks!

    Not sure if you have the same style of Morse controls

    Should be in your manual. If you dont have that, you should be able to download it from Sea Ray

    Hi Mike, I have the same issue with my throttles on 1991 350/370 Sundancer . Like to know if you were able to find anything in the manual or else where on the adjustments. I have been looking with no luck.Appreciate any help you can offer.

    You all have those same throttles. All the inboards from that era had them, just like all of the next generation SRs had the gold knob throttles. I had them in my '89 340 Sedan Bridge. Make the adjustment that Mike posted and should solve your prob.
