hello ladies and gentlemen I very recently bought a boat for the first time,it's an 89 bayliner 1770 and it came with an 85 horse force,I know very little about boats but alot about quads/dirtbikes/cars/trucks etc,I recently took it out for it's maiden voyage(my maiden voyage the boat has been out before) to test it out,I ran into several problems along the way, first off when I launched the boat and tried to back away from the boat launch it started fine and idled fine but when I trimmed the engine down to submerge it it stalled several times,I figured it needed to be warmed up as 2 strokes can be rather picky sometimes,it put it down far enough to get some water and waited, after few minutes and several tries I was finally succesful at backing away,I turned around and started motoring away,the boat stalled a few times but would start right back up and go again, these things I can contribute to it not being used in 2 years as the previous owners had told me and I had expected a few problems, but what happened next has me baffled, the motor started running better and stalling less but I was only able to get to about half throttle,I ran around the lake like that for about 20 minutes, I then figured it may be the linkages needed to adjusted or something,i tried to look at them but they seemed to be working fine,I took it out again and all of a suddent it opened up to full throttle and I was on my way,this lasted about 10 minutes or so,i stopped to check out the fishing for 20 minutes or so(never got anything) and when I started the boat again it was back to the half throttle thing again but in reverse it seemed to work at full throttle,I was running out of daylight so I loaded the boat up and came back home, today I was working on the trailer it needed new lights and new safety chains but I didn't want to touch the engine til I talked to someone or something,I have to include that the boat did have half a tank of fuel when I bought it,I topped it up to full tank with premium,added carb cleaned and sta bil to it and of course oil,boat seems to work fine at home out of the water with the muffs on revs out etc, just hoping somebody has an answer here for me as to why this motor is doing this, thank you in advance for your help.
