Yamaha 60/40 or 90/65?

Postby Nater11 » Tue Feb 05, 2019 10:34 am

Explorer is building a 162 for me and I’m not super framilliar with OBJ’s. Is the extra 25hp worth 97lbs on a 16’ 66” boat? Any experience with the new 90/65? Originally the goal was light as possible, but research is saying 60/40 is a slug with more than 2 dudes. Thanks.

Go with more HP. It will be a slug with the 60/40

I'm not positive but I don't think I've ever seen an Explorer with anything other than a Yammy. If weight is an issue, ask them if they will do an ETEC 90/60. Way better power. Less maint, lighter and 10 year warrantee. My buddy has one on his 16' Koffler and its the cats a$$.

I am a total newbie to jet boats although I’ve been boating for decades... I just went through what you’re going through right now but in the “used market”. I picked up an ALMAR Lite 17 that is 6” longer but 8” narrower than your Explorer. My hull weight is 470 lbs. I ended up with a NOS 1986 Merc 115 outboard that’s really nicely tuned... It weighs a bit under 300lbs and is obviously a two-stroke. I also have a 90 pound kicker on the back. With 600 lbs of men, a 80lb dog and gear, coming out of the hole feels really fast to me and my jet boat—experienced partner...WOT is right under 40 with that crew.

I feel I could add another fisherman easily and probably be good for what I intend to do which is fish local Portland/Or Coast rivers and spend a lot of time on the lower Rogue.

I almost bought an 18’ Smokercraft sled that had a 60/40 on it and am really glad I didn’t now! I was worried about the small motor. I’d definitely buy as much HP as you can get! Also, really try to test drive each engine on the boat if you can.

I figured if I have to buy a 400 lb four-stroke someday, I’ll lose my kicker and buy a MinnKota for the bow....

Good luck, looks like a beautiful boat!

A 115/80 may be the same weight as a 90/65. Manufacturers often use the same basic motor in different states of tune to achieve incremental differences in horsepower. Buy as as much horsepower as you can run on that hull and you'll never regret it.

The factory Merc jets in 115/80 and 90/60 are the identical powerhead and weight. Roughly $2K difference. I have the 115/80 and love it. I think its a better option than the yammy personally. Better pricing (in Canada anyway) and a 20" shaft rather than the 25".

I work at a Dealership that sells Explorer Boats. I have heard mixed reviews on the 90/65 from my customers. The bigger motor doesn't seem to give it anymore speed and turns the boat in a bit of a bum dragger, but the bigger motor gives the boat way more lift and load carrying capacity. I think it depends on what you are doing with it. A day trip fisher, play boat get the smaller motor. Multi day trips with lots of gear or hoping to be packing home a moose get the bigger motor. Or upgrade to the 172 with the 115/90 same weight as the 90/65. The 172 has turned into our most popular Explorer boat.

Thanks for the info guys. Just thought I would put in here. I talked to a guy on the Alberta outdoor forum who recently traded his 60/40 for a 90/65 on a 162. He is happy with the decision; however, told me that the static draft is way more and the rear end weight is very noticeable. Coming off step quickly while headed downstream can leave nearly no freeboard on the transom due to the wake. For pulling his kids on a tube around the lake, he said was way better.

That would be me. (just signed up here trying to learn more) I'm sure Dave at Explorer mentioned the rear tail fin that they can add to the back of the boat with the 90/65 to help with the issue of water coming over the back. It comes up at about a 30 degree angle right on the rear corner. I haven't done this yet because since I'm aware of it I typically avoid sudden stops, but I know I will regret it one day when I'm forced to make that sudden stop. I've got a swing over ladder on the rear that would be in conflict with this rear fin otherwise I would have most likely added it on already.
