    Strangely deteriorating performance

    I'm having a problem with slowly deteriorating RPMs at wot, as well as increasing problems holding idle. We're working with a '77 85hp. Over the summer I've been noticing a decrease in WOT by about 500rpms every 15 or so hours of use. I've also been having to adjust the idle up by increments...

    Gah - silly little mistakes.

    So I decided to do a decarb last night using the 1gal 1can method on the muffs. I start it up and run it for a few minutes, normal operations etc. fine. Shut it down, turn hose off, take a break. I come out for another run, start her up and . . . la la . . . holy . . . I FORGOT TO TURN THE...

    Prop experiments

    I currently have an over-propped boat and need to go down in pitch. My spare prop is what I believe is the right pitch. I'm considering putting it on and trying it out. If it performs correctly, I'll buy a new or rebuilt prop and keep the one I have as a spare. However, there's a small chip in...

    8hp link and synch question

    '86 Johnson 8hp. The factory service manual instructions are a bit vague in one spot. It says to run the motor with the throttle "mostly closed" and set timing to 9-degrees. What is "mostly closed" (1000 RPM?), and is that 9 below or 9 above?

    Gast tank sender

    New tempo tank and on two different gauges it reads empty with 1/2 a tank left. I haven't removed the sender yet to look, so maybe it's just painfully obvious. But, any ideas for tweaking a sender to read better?

    '86 8hp franken carb

    So, I've been doing a little research on my carb, which doesn't seem to match the parts diagram. I've also been having a bear of a time trying to get the carb adjustments to go by the book in the link and sync. So I thought a little sleuthing may turn up something. Here's what I've found so...

    Just some feedback on interdeck

    As some of you know, I installed a new floor in my Starcraft this winter and covered it all with interlux interdeck. The more time I spend in the boat the more I really like this stuff. Last weekend was the kicker. My fishing partner, in his infinite wisdom, decided to bleed out a halibut IN THE...

    '86 8hp misfires when warm

    It takes a long time to get this to happen, but if I run this engine for about 1/2 hour it will begin to misfire. Sometimes it goes away, then comes back. I isolated it down to cylinder #1, then switched coils. It stayed at cylinder #1. I'm guessing the power pack is on the way out, but before I...

    86 8hp mixture adjustment

    Anyone have any tricks, mods or unique tools to make this adjustment easier? It's just about impossible to get a screwdriver to the adjuster. Who thought that configuration up?

    Another Which prop for me question.

    I'm currently pushing a 18' Starcraft SS with a '77 85hp Johnson. The current prop is 13x19 and turning 5000rpm at full throttle. I'd like to re-prop to get 5600 or better. Any advice welcome.

    Manual question

    Looking for a used manual for my '86 8hp. I see one on e-bay for an '88, any major differences?

    New kicker - can it hook up to my remote?

    So, I went and bought an '86 8hp Johnson to replace my heisted 15hp kicker. I think it'll be an all-around better trolling motor for my boat. So, at least there's some kind of positive outlook. Anyway, looking at it, it's not real clear if I can hook my remote console up to the throttle...

    It just figures

    All that work in to my 15hp to make it water tight and getting it running like a top and what happens? It gets lifted off my boat at lunch coming back from the lake. Here we go again. I think this time I'll be shooting for an 8hp though. I think it would troll better at lower speeds...

    Still have idle adjustment issues

    Okay, I think I'm officially at my wit's end. Just to refresh your memories - '87 15hp. Trying to set the cable off the remote to set idle. I have no more turns left on the trunion. And to go down the list: Freshly cleaned out exhaust tube New rings Carb rebuild New charge coil Link and sync...

    Break-in question

    Just did a ring-job in a 15hp. Gaskets, seals, and rings; nothing else. Do I need to do a full break-in procedure w/ 24:1 mix and all that, or just go easy until I seat the rings good?

    15hp idle issue update and charge coil question

    I had a post about not being able to adjust my 15hp into an idle with the normal cable adjustments. Well, I found out why. Nothing was really making sense so I decided on an invasive inspection. After pulling the powerhead and removing the exhaust tube I discovered an almost completely carboned...

    '87 15hp idle adjustment

    Trying to adjust the idle setting in a 15hp today. It seems to idle well with the remote throttle slightly engaged but not with the trottle all the way back. I can't take any more slack out of the cable. I had originally thought it was a stretched cable, so the one I have on now is brand new -...

    Funky fuel pump issue - '85 9.9

    Not a question, just reporting an oddity I figured someone else could maybe use. So, yet another kicker landed in my lap. They seem to be falling off trees lately. Anyway, this one needed coils and a carb kit - so that all done I go to test it out on the boat. It wasn't pulling fuel off my...
