Hey guys need some help.. I have an 84 Sea-ray Seville that I helped my uncle rebuild.. All was good except shift lever was tight and had a real hard time getting the handle to pop into neutral for throttling warm up. So had a spare shift lever with old cables attached. I removed the old shift lever from the old cables and did the same to the shift lever on the boat. I made no cable adjustments. Before I changed the shift lever I ran 40 mph at about 4200 rpm WOT now with the new shift lever when I am able to hit 40 mph its at about 5500 rpm and 30 mph is about 4200rpm.. This all makes no sense to me and I am worried at running that high of rpm. Could the different shift lever make one of the adjustments move or be off?? The only other issue I have is the classic Mercruiser stumble once she's really warmed up and wanting to die out when you put her in gear unless you catch it right. Since I got her though she seemed to do that.. Normally idles about 6-700 but once she has really warmed up over the day she wants to idle at 4-500 which is the only time she seems to stumble when I try and put her in gear.
