Is this enough motor for my boat?

Here is the deal....I own a 1987 basstracker tournament V 17ft. boat that currently has a 1987 Mercury 60hp 3 cyl 2s. This motor is shot and needs replaced. Although the boat is rated for up to a 90hp the 60hp seemed just fine for what I use it for....it ran around 25-30 mph depending on how much stuff I was hauling around. I keep the boat up in Canada and only use it maybe three weeks a year.<br /><br />My question is this. I can get a really good deal on a 2000 50hp Mercury four stroke (non EFI) that the salesman says is enough motor for the boat based on what I have told him. He says that HP is measured differently on the newer motors than it was back in 1987 and that the 2000 50 hp four stroke will perform just as well as the 60 hp two stroke that I have (and if it does I'd be 100% satisfied).<br /><br />Is what the salesman told me true....and will the newer 50hp 4s perform as well as the old 87 60hp 2s?<br /><br />Thanks for any advice.

That's a tough one, the salesman is fudging a bit, but if you aren't looking to set any speed records you could be fine. 10hp is almost a 20% loss in power. I ride in a similar rig, and with 3 of us(small powerful guys), and we scoot along just fine, about 30mph max. Maybe someone else will answer that has tried the 50hp on a similar rig. I don't think it matters whether 2 or 4 stroke motor, 50hp is 50hp. Chief ;)

Re: Is this enough motor for my boat?

I believe they changed to rating horsepower at the prop in 85.So your old motor is rated the same way as the new one.Generally speaking a 4 stroke is a little slower out of the hole and slightly slower top speed than a comparable 2 stroke..The 4 stroke is heavy<br />probably as heavy or heavier than your 60.The 4 stroke is much more complicated than the 2 stroke.It requires more maintenance.And depending on your ability more professional maintenance.I dont think you will be happy with that motor.I think the 60 is about the minimum for half way decent performance on your boat.<br /> If you can bite the bullet give the new Evinrude Etec a close look.The infomercials sure make them appear amazing.Up to 7 years warantee.<br />Is as cleane,faster,lighter,simpler than a 4 stroke.Im even thinking of one after all most 20 years with what I thought was my last motor.<br />A 88 Evinrude 50 2 stroke.<br /> And from what I have seen posted very reliable.<br />And now they have mid sizes available.

It's shaft-horse-power on the old motors vs prop-horse-power on the newer ones. 60hp at the crankshaft is less than 60 at the prop, but 20% less? I doubt it.<br /><br />still, how good a deal? 50hp is probably as much power as Tracker offers on the base 17ft deepV package today.

Re: Is this enough motor for my boat?

I think you would be disappointed with the 50, Patrick.<br /><br />As a general rule, I find that most boats perform well with at least 70% of rated HP. The 60 was on the edge of that and the 50 falls well below it.<br /><br />I am a big fan of EFI 4 stroke outboards, so I don't have the same opinion of them as Steelspike, though we agree on most things.<br /><br />We agree, for example, that you need at least 60, better 70hp for decent performance.<br /><br />Now, back to your Merc 60. Why do you say it is shot? That engine isn't 20 years old yet and should have another 30 years in it with care.<br /><br />I suggest a better deal than the Salesman offered: Fix the 60.<br /><br />Tell us what is happening that shouldn't and what isn't happening that should. I'll bet we can get it running like new for a fraction of the price of a new engine.

I'm sure the motor can be fixed as in addition to the stator needing replaced the reeds are shot and it would require a total tear down to repair it....since I won't be doing it myself the labor costs alone would be more than the motor is worth (although less than new). Given that, and the fact that I use it maybe three weeks at the most in Canada I have to have a motor that will work for me when I'm up there....can't spend three or four days at a time working on something when I only have a week to fish...I need something more dependable. I'm really not worried about top performance...I just need to get where I want to go without having problems all the time. I'm happy with 25mph.

All I can say is I sure like my old 4 stroke. It's a 55hp Bearcat on a fiberglass 17' trihull, if you're not into speed I would go with a 4 stroke. Four strokes are quieter, (at least mine is compared to my 2 strokes), no oil/gas mixes, not as much smoke, etc... Although I haven't seen what those new 2 strokes can do either. This coming from a nobody who doesn't know much about boats. :)

Reeds and stator can be replaced in 4 hours by a slow worker, Patrick.<br /><br />If you just want a new engine to use 3 weeks a year, get one, but don't give your 60 away (or send it to me :) )

JB....I had three different marinas up in Ontario give me a quote for fixing it.....I forgot the power pack was shot to....the cheapest quote I got was $1,200...that's Canadian funds. I can pick up the 2000 50 4s for $3000 Canadian with a one year warranty.

Well, Patrick. If your only option is to pay someone else to fix your 60 what you say makes sense.<br /><br />I still think you will be disappointed in the 50 but it is your boat and your decision.<br /><br />Good luck. :)

JB...thanks, that's why I'm asking the question. Don't want to get it and be dissapointed. I spoke with the marina this morning, they told me If I got up there and didn't like it I could bring it back for a refund....guess I can't argue with that.

Some rambling comments because I have been and will be in the same position.<br /><br />You still have a situation where you can get your old 60 working for $1800 less than the 50.<br /><br />I've never made this change, but I would really think that the 50 4 stroke would give you significantly less push than the 60 2 stroke. It's 15% less HP and probably significantly heavier. This may be just a little, but acceptable, decrease in performance, or a night and day difference if the 60 is close to being underpowered as it is.<br /><br />The 4 stroke has some advantages as you know, which might be advantageous for your use - better idling, quieter, better troller, less smelly, probably.<br /> <br />You'll need to ask, but a professional shop will usually give you some sort of warranty on major repair work on the 60 - maybe even 90 days, which would probably be as good as the 50 HP's 1 year warranty since both cover one season?? <br /><br />If the "repair shop" is as trustworthy as the shop selling you the 50, and can get the work done before you need it, it is still worth considering repairing the 60. It will likely push your boat better and, if repaired well by a reputable shop that will back up its work, be just as reliable as the used 50. <br /><br />I'm totally with you that reliability is more important than a little bit of performance difference, though. If you really think the 50 will be more reliable, and your only loss is a little performance, I'd go that route.<br /><br />I'd also ask exactly what the money back guarantee is. My guess, unless proven otherwise, is that you'd get your money back only if you put it towards another engine in their inventory. Which means you could indeed get sucked into spending even more money on a larger engine after all, making repairing the 60 an even better deal.<br /><br />Just some thoughts.<br /><br />Good luck, have fun.

I would be happier with a slightly different deal. How about you pay the marina for installation and rigging, plus an extra $100. Then you can try it out and if not satified, they can just remove the motor from your boat. This would be alot easier than trying to return it and get your money back. If the dealer will not go along with it, perhaps they really do think it will be underpowered.

Re: Is this enough motor for my boat?

If you use it only a few weeks a year in Canada then you probobly can get by but I have been up in Ontario when I wished I had a jet to get down the lake to safety. If the deal is so good and you do not venture far from home then it would be a good deal. If you venture farther then get the most HP you can. Just my penny's worth.

Re: Is this enough motor for my boat?

Does the dealer have one mounted on a boat something like yours, to take a test ride in, so you can get an idea of how it will be, or maybe another guy w/ a like set up, to take you for a ride. Just an Idea, good luck.
