1995 Merc Question?

4 posts in this topic

Our 1995 90 HP Merc tiller starts to miss half way through the summer each year. We install new spark plugs every spring, and have to put in a new set half way through the season, then it runs great again. Is this normal?

I wouldn't call it typical.

Do you do a lot (and I mean a lot) of trolling with this motor?

It's possible the cylinder gets loaded up with fuel and fowls the plugs.

What do the plugs look like when you change them? Do they all look the same?

mm, thanks, we have a 15 hp Merc for trolling, so the 90 is used primarily to reach our fishing spots. We do most of our fishing on LOW so 3 to 10 mile run's are the norm. All 3 plugs look the same-wet.

Personally, I've never much liked the way my 96 Merc 90hp runs from about 2500 RPM and below, it's rough, spits and sputters, shakes a lot, etc. The carbs have been gone through and no real difference in how it runs there.

Runs great from 2500 to WFO.

Can't say I've had much problems with plugs fouling if I'm keeping the revs up. But, if I putz around a while it'll eventually load up, seems to clear out pretty fast once you pour the coals to it.

I've probably put only a few sets of plugs in mine. In fact, I think I still have the factory plugs in the cubby hole.

Mine has the surface gap plugs in it, yours too?

      Refresh my memory... If we just go into Trout Lake for the day, we are not required to get a permit in advance. We just fill out the form at the portage. Is that correct?

      Yeah that is the one.

      Thanks for the information!  Whenever I'm moving, I use a ram mount to secure my bow mount. I just got the Ulterra this spring.  I had a Terova on my last boat. I was going across the lake in 3 footers and the locking mechanism failed and the motor deployed. Ever since then, I secure it for a piece of mind.

      One of my trolling motor batteries decided to take a crap on me so it didn't have enough power to go into the wind so  that made it tough...we tried a few drifts in areas that looked good for eyes, but didn't pan out....We went to a different spot and started catching nice sized gills on the rigs so we decided to just say screw walleyes and go for gills (I could tell the gf wasn't digging the 20mph wind in the face lol). So we went to a spot I've fished in the winter and ended up catching a 20,24"...We caught them not to long before we left right in the same area.... I've never fished it in the summer before so I wasn't expecting much...The look on my gfs face when she caught the 24 was priceless though so I was happy.

      In no way am I trying to fire up a catch and release vs catch and grease fight.  Admins, please delete any comments like that. I am curious about everyone's thoughts and knowledge on mercury in fish.    It seems Walleye are always the riskiest fish to eat via DNR and MDH surveys but I know the fishing for eyes is such a tradition up here. A lot of walleye are eaten in Minnesota every year as well as Pike and Bass which also can be high in mercury because they are high on the food chain. Does anyone worry about it or is this something that is overhyped? I'm a bit careful where I fish because my wife is pregant and I don't want her eating too much mercury. I'm still kinda new to the state so I trust the knowledge of locals more so than DNR in a lot of situations.    For example, in TN (where I moved from) our DNR says do not eat ANY fish from the Mississippi river. I'd say it's pretty nasty by the time it gets that far south but there are river rats as far down as Louisiana eating catfish and bass all year long and you don't hear of them dying from mercury poisoning or having other effects of it. At least not thay I've heard or read.    I'm very curious to know your opinions on the matter. I don't catch many walleye anyway but I do love eating Pike and other fish. It's so satisfying to work hard for a fresh meal but do I have to continue to be super cautious of what lakes I eat a Pike from? Seems like the closer to the metro, the more dangerous it can be...or is it? Some of the huge lakes up North are full of mercury too.

      Well it end up being 2 broken live well pumps being broken.  The pumps would pump water into the live wells but also be spraying water into the back compartment of the boat.  That's where my water was coming from.  I would like to thank those that replied suggestions back.
