Author Topic:   '84 18 OR - 90 HP Honda

ECUSeaPA posted 12-17-2001 11:26 PM ET (US)
Repowering a 1984 OR. Not interested in speed, but I am aware of the problems with underpowering. I'm stuck on 4 strokes and would like to buy used. That eliminates the Yam F115 as they are just not on the used market. There's a 90 HP Honda on EBay, '98 Model. What performance could I expect from that motor?? I'm willing to sacrifice a little performance for price and 4 strokes. I know the Honda is a proven motor as well.

Ecusea,
A 90 hp on an Outrage is underpowered, period ! Keep your eyes open there are always motors available for sale. Check Ebay..in fact there is a 115 Yammie for sale there right now.
If it was me I would wait until a V6 came along, preferably a Yamaha.
Patience my friend. I bought a Yammie 90hp on Ebay from a local guy for $1300 (controls & prop) that is the cleanest I;ve seen in years. (FW motor)
Good Luck,
John

Go get 'em.

I agree with John's assessment here 100 percent. 90HP is not enough. 115HP is the lowest you should go on the 18 Outrage.

Dennis, assuming a gross weight of 2300lbs (my guess 1200hull + 400 engine + 100 fuel + 200 pilot + 400 misc = 2300), the theoretical max top speed should be around 35.6 mph. I ran a 21 Revenge with a 90 merc for a couple of years and it would hit about 35mph and cruise all day at 28mph. The hole shot was all not bad either... NOT a ski boat by any means! The 90 hp should work fine for you but I would recommend the 115 EFI Merc 4 stroker... Happy Whalin'.. clark.. Spruce Creek Navy

You also must consider the variables, water condition, wind, current, and air temp. can affect your outboards performance. In addition, an underpowered boat could be harder to sell! I have a 150 on my 18' and use every bit of it.

OK, sounds reasonable, BUT, I'm infatuated with 4 strokes, and the Honda has a great reputation. I do have plenty of time though.

I'll have to 2nd the 150! I had a 84 with a yam 150...it was great!! You'll really be sorry if you underpower especially if/when you go to sell.

Isn't infatuation a "passing fancy"? When you seriously look at Honda's offerings for an 18 Outrage, I think you will become less infatuated.
The 90 Honda is not enough, and probably not as strong as the Merc 2 stroke 90 Clark mentioned, and the 115's and 130's are simply huge and heavy, and not all that great performers compared to the competition. The 115EFI Mercs and Yamaha's are smaller, lighter and faster, and the 135 Merc Optimax is the same. Maybe you should look at Suzuki also, or even the forthcoming Fichts. Unless you're obsessed with brand loyalty, Honda seems the least appropriate brand for an 18 Outrage.
Finding any of these more appropriate engines used is not going to be easy. I would think the Merc 135 Optimax would be your best chance, since they have been around for several years now.

You are right. I think the EBay Honda is up to $4500 now anyway. The F115 would be a better fit without question. My son will be using the boat a lot, and while he' very responsible, I'd really rather the boat be limited to about 42-45 miles per hour. I suspect the 150 would push it much faster.
The Merc 135 would be a good fit but I'm partial to Yamaha / Honda and then Suzuki. I'm starting to have some reservations about Suzuki due to parts/service issues that others are having. I really wanted to get away for the 2 strokes too.
I'll keep looking. Thanks for the input.

Then I would agree, the Yam 115 EFI 4 stroke is your best bet. It is the same engine as the Merc 115 EFI. I would also think that EFI is the way to go, as has happened with our cars. All of the 4 strokes seem to be heading in this direction. All of Mercury's four strokes, 25 hp and up, except the Yamaha shared 75 & 90, are EFI's now.
As an owner of EFI engines, I can say they're highly reliable and superior to the old carburator technology. When I bought mine, in 1997, I asked the top service guy at my Mercury dealership about spending the extra for EFI models. He said, "buy them - all I can tell you is once they leave here, we never see them again". He was right. After 1000 hours, the only thing, on just one of the engines, that had to be replaced was a rectifier! No problems with fuel delivery, starting, idle adjustments, idle speed, etc, at all. The little micro chip & sensors do everything to keep them running smoothly, all weather conditions.
