New Motor Or Not?

12 posts in this topic

OK here is the problem...I have a old 1988 Lund Renegade in decent shape except the motor is also a 1988. I luv the boat but I am also a fan of reliabilty. I have had zero problems with the current 1988 mariner 45 hp other than speed is a issue and trolling is out of the question. I would luv to stick a new 90 hp motor on it which it is rated for or should I sell the whole thing now and look for something different...I will say this boat is big enough for my family and it is rock solid on the water...I even get lots of compliments on the looks...So the question stands sell boat or buy a new motor????

That motor is as rock solid as they come. It is thirsty, and can smoke a bit, but it will run forever. If you are seeing that it isn't trolling properly, I suggest you have a mechanic clean the carbs. Or you could do it yourself, it isnt that tough.

Because that is about the smoothest trolling motor, and it will troll down to a sloooooooooooowwwwww walleye troll no problem. We have a '82 Merc 50, which is the same motor exactly.

I can see if you want more HP, and I can see why. But don't worry about that motor, sounds like it just needs a little service to get to "like new" performance again.

I am a black motor fan, but the e-tec 90hp would be a dandy replacement if you go that route.

Good luck.

I agree with Box, in the right hands, these can run like a sewing machine.

Sorry guys, but I hated my '85 50 Merc because of the limited turning radius. I was warned about that before I bought it (new) but it matched the boat so nicely smile

Lots of power, smooth, slow troller, but turned like a battleship.

i have the same motor it trolls down just as slow as a four stroke it will put along all day . One thing that i did do this year is that i switched to amsoil synthedic oil also i mix my oil and gas i took off the injector system. very little smoke i can troll for an hour with very little build up . the only problem i have with the motor is that it likes gas.i can backtroll all day

I have the same boat and motor! My motor is still strong and I can slow it down to almost nothing. Fishing is awsome with it, speed is not an issue for me. I get thete and have fun.

The newer 90hp Mercs probably are different, but I have a 96 model and have never been really happy with the way it runs at low speed (< ~2000 RPM). It's rough, in my opinion, and doesn't troll down very well unless you consider speed trolling for Northerns adequate.

I've had it to a couple different Merc authorized/certified places and they both said it's running fine.

OTOH, above this speed it runs fine, no complaints at all, and pushes my 16' Sylvan Pro Select to 40mph GPS, sometimes a bit more or less, depending on water, wind, and load.

Also, have you looked at the prices of new motors? Yikes!!

A new 90 hp is going to run at least $7000 plus installation. Your current boat is 20 years old and even though it's in good shape, that's a lot of money to spend on a motor. Personally I'd trade the boat and look at something new that could last you another 20 years.

Thanks for the input guys...I'm still up in the air...old boat new motor 7K... OR newer boat with older motor along with it...They say these LUND hulls will stand the test of time so there is a pretty good chance I may test that theory out with a soft on gas new motor...Looking at E/tech 90, or Honda 90...Lots of research to do....Thanks again...

Hey Viking, while you are considering, make sure to thoroughtly check the floor before adding a new motor. At that age, it might be starting to get spongy. I have rehabbed boat and pontoon floors, and it really isn't so bad, but you will want to do it right.

That hull will last forever, and it is a good boat that doesn't "look old". Even if you would have to put new floor in (about $600 or so total, and I recommend vinyl flooring instead of carpet) I would recommend looking at some new seats, new motor, new floor and if you want HP a new motor. It will cost a bunch, and maybe not give you the resale if you sold it, but you would have a great and "truly new" boat for under $10k easy.

good luck, let us know what you end up doing!

I went thru the same issue with my '88 Renegade, only mine had a weak 90hp Merc on it. Every dealer I talked to said they would do it but none of them recomended it stating that the value of an old boat/new motor isn't there.

I sold my boat on hsolist for $3200 and picked up a like new 10 year old Pro-V for $10K, about the same to boot as a new motor but I got a whole lot newer and nicer boat that is worth alot more than my old boat/new motor combo would have been. Something to think about.

I've got an 88' Mariner 45hp that runs like a dream.....I can understand speed being an issue but for trolling and general reliability that's a great motor. I suggest what other have said already and clean the carb. or rebuild it. Good luck.

    • I have been meaning to try to stick a yote too whenever I was out I hoped one would show up instead of a turkey.
    • should have set up in the grass! Uncle went back for evening set up at a pinch point hen and tom came through to go back to roost but no shot!
    • Beside the fun of fooling a turkey and sticking it witj my bow,this is why I love turkey hunting. Slow smoked with apple on the pellet smoker. 
    • Does anyone have a water driven backup sump pump? They look like the cats meow if you live in town. Or does code even allow them? If they are not allowed what is the best battery backup ones?
    • Got out Saturday morning. Perfect weather. Jakes and hens. Had a new group of 6 hens come in with no tom or jakes.   Did have a yote come out of nowhere right into my dekes. 12 yards. Just as I was drawing on it , it must have scented me and booked. A second yote crossed about 50 yards out. Sticking a yote is on my bucket list.   All in all a great morning.    
    • Good season Wild, onto next year. Should be some changes but I don't expect us to do anything crazy. Need to sign Granlund and Nino and that will use up a lot of our cap space. Can't afford Hanzel and possibly Haula and Vegas will be taking a player off our hands. I'm more interested to see who can sustain or step up their scoring next year or if anyone regresses. Granlund, Coyle, Nino, Zucker, Dumba, Spurgeon and Brodin all had career years, those are good problems to have. They showed us a lot but I think they still have room to grow and that is what we need. We have a nice cast of vets but they are likely too old to lead us to a cup, they would be in more supporting rolls. Hopefully our now seasoned young core and continue to build on their impressive seasons. Always disappointing to lose, even worse when you can't score against your old coach but I like the our team and hopefully we can keep getting better.
    • I'm not the most techy 40yr old out there, so I will try to explain what I'm looking to do and hopefully someone can point me in the direction I need to go. I have a cabin in the Chippawa National Forrest, no phone at the cabin and our cell phones dont work at the cabin either. My teenage son wants to take the wheeler and go riding alone. I worry he's going to get lost or if the wheeler breaks down he can't call my cell for help. When we drive my truck around; the gps in it works all the time.  I know I can put a GPS app on my sons phone so he can track his route in reverse to get back to the cabin. But what if he breaks down?  Does anyone know if there is a gps app that I could "pair" up me and my son's phone so I can see where he is at? kill 2 birds with one stone per say, he can use it to navigate himself on the wheeler and I can see where he's at incase I need to rescue him.  Thanks for the help.
    • Hit the Red River over the weekend for the 2nd time this spring. First outing wasn't great with a handful of smaller cats all under 10lbs. This weekend was a different story as we ended up with 15 cats Friday night. 5 over 10lbs, 2 of which were high teens fish. All caught on cut river bait.  Cats were on the shallow side of the river. Water was high and flowing pretty good. All fish were caught and released. Great night of fishin w no bugs to bother us and very nice weather! Gonna give it another whirl soon in a boat this time. Have a look!!
