"i just bought 1986 70 hp vro

"i just bought 1986 70 hp vro johnson with remote controls. ran fine in driveway with water ears. compression reads 100 through all cyl. when i went to ramp to launch, motor stalled when shifted forward or reverse. it starts right up and idles nice in neutral, about 1200rpm. looked around , found some minor fuel leaks, replaced all fuel lines from tank outlet to carbs, including the primer ball, still stalls when i shift, if i push right through low speed in gear, it runs fine at high speed, but when throttled back , stalls at low speed in gear. did linc/sync procedure as described in servive manual, never touched wot timing advance, but dont rally get it. if i set cam follower at throttle plate as described in book for idle timing, then check timing, to adjust timing, you are moving throttle plate past center of cam follower. i think i am missing something, it seems that to get this right, you are changing your earlier settings. if i raise idle screw, idle will be to high for safe shift. when i look at cable movement, throttle does not advance until about 1/3 of travel through forward range at the control box, is this right. my yamaha throttle advances as soon as i click into forward gear. one other thing with the fuel filter, it does not stay full to the line when idling, it can hardly keep a 1/2in or so in the bottom, if i pump ball it fills up, but runs right back down. any thoughts or help would be greatly appreciated. thanks"
 
"Start by checking idle rpm IN

"Start by checking idle rpm IN GEAR forward, and boat moving freely. Should be around 750-800 on that engine. Next check if the exhaust relief holes are ABOVE water.
The fuel-filter normally only gets half filled. To check the fuel pump (VRO) it should give a 'click' every 20 sec (roughly)."
 
"the idle in gear drops to abo

"the idle in gear drops to about 570rpm then stalls, if i raise the idle to 750-800 in gear, it is 1400 1500 in neutral, isn't this way to high for safe shifting, the boat was operated in upstate lakes 3000-6000ft above sea lea level, it is now on coastal ny waters, could low speed orifices be wrong. exhaust relief holes are above water. vro clicks every 20-25 seconds. thanks for the response."
 
"Dan, I just bought a boat las

"Dan, I just bought a boat last week that has the same motor a yours the guy i bought this from had 1300.oo done on the motor from fuel lines to rebuilt carbs fuel pump,power pack ect. He told me his did the same thing as what you are describing i took mine out today i noticed the motor idled @ 800 rpm but when i shifted in fwd it tried to stall until i gave it more gas and the same in rev. I wonder if it aint the nature of this motor. I called the marina that worked on this motor and he said he wouldn't know anything to do for this. he said he has heard several people say the same about this motor. if you find something out let me know thanks joe."
 
"the motor should be idling at

"the motor should be idling at 750 -800 in forward gear, maybe you can just raise your idle. i brought the boat to a shop where i trust the mechanic, he has many years of experience. i was trying to avoid this because his shop is 40 miles or so from here, but outboards are lots of $$$$ to replace if you mess something up. hope to have it back in a few days, i will let you know about repairs made, and how much it cost. the problem with most shops is that they do not know how to repair, they do know how to replace expensive parts , sometimes needlessly, while trying to make the repair. good luck"
 
I just bought a 66 traveler bo

I just bought a 66 traveler boat its got an 82 evenrude 70hp outboard motor. When I launched it the motor shifted into reverse fine. Now when I shift into the forward gear the motor stalls imediately. starts right back up but stalls every time I shift into forward. it will run fine in reverse. I just can't go forward. I don't know anything about boats or motors but I do know that its a little hard to fish from the boat going backwards. thanks any advise will be apreciated
