I have posted several times about putting twin 70's on my 18' Whaler Outrage and do appreciate the response. The Marine rebuilder I was working with was rebuilding both motors. I called him today to make final arrangements and found they are 1994 60's not 70's. Both are Johnsons. Shocked and disappointed; to say the least. He said from 89-01 the cubic inches were the same with little difference except in Carburators. It would make very little difference in the overall performance. WHAT do you think; and what you advise. I had previously told him I wanted 13 !/4 X 19 props and we had that worked out. If you know of anyone changing over to single engine from twins, I might be interested. Merry Christmas to all !!!!!

I wouldn't be concerned with the loss of 20hp over what you had anticipated. Top speed should only drop by 2-3 mph and very little other change having 120 versus 140.

I would be concerned since the minimum to plane the 18 is 75HP. There is no way you will plane the boat on a single 60HP and you are limping home on what amounts to a kicker, abet a really large one. I would actually be concerned with putting anything less than a pair of 75HP on the 18 but then I prefer to have max HP or better.
I assume your going with twins because you boat off the coast and want twins for safey reasons? If not then maybe going home slow if one engine dies is not an issue

There are many people with twin 70 hp motors on Outrage 18's of which I was one.
A single 70 hp will plane the boat satisfactorily. I am not sure about a 60 hp.
Here is an article I wrote on the performance of twin 70's on one of my prior Outrage 18's.

My Outrage 18, t-top, plenty of fuel, too much beer on ice and 4 adults planes fine on 50hp. With just me aboard and full fuel will run about 28 mph. Several Outrages with twin 70s have been known to easily plane on one motor. Can't say it will plane on one motor but doubt loosing just 10 hp over a 70 hp would prevent it. There are few situation having the maximum rated hp is of any benefit or used other than to be able to get a better hole shot or additional speed once on plane. I understand some people have very good reasons to go with maximum power but the majority of times it's just what happens to be on the boat when purchased.

How could the guy rebuilding the motors not know from the beginning that they were 60's. Is he jerking you around? Are motors something he's trying to turn over for a profit? If you haven't paid for these yet, I'd pass on them. Sorry, that's just how I feel. I can't imagine an 18 being able to plane on a 50hp. I call bull. Sorry, don't believe it at all.
I have an 18 Outrage with twin 70's and would not want less power.

I do appreciate your observation; and I agree. I have been giving this some thought for several yeears. I first came in contact with this man on E-Bay. His record is good and we live about 150 miles from each other. Three or four months ago he had a 70 hp and I got his number and we talked. Three weeks ago I called him again and had a man ready to buy my motor, which I have sold. I took notes on what he was going to sell me and the year model. No money has passed hands. Today I told him I was going to be in his area Thursday to draw up an agreement and that's when the 60's came into the conversation. Again, I thank you and I am going to pass but keep looking.
If you would, post what the top speed is with your twins and what props you are running.

I'm running Yamaha 13.25x17 and I need to go to 13.25x19 to bring my redline where it should be. I'm at 38 or so mph. I plan on getting new props in Spring. Motors are one hole up. I can't really plane on one motor. I think with the new props I will be able to.
Was that rebuild guy in PA? There's a place that rebuilds that has a very bad reputation.
If your transom doesn't have holes for twins, then I'd stick with a single. To each his own.

I think it's called Blackbird Industries.
I can't stand people who lie or withhold critical information regarding the stuff they sell. I know of one person, who used to post here who was like that and it really made me mad. The guy had plenty of money, not that that should affect honesty, but he really had no need to be dishonest. Sometimes you gotta take a loss on something like a man. What was the question?

The man I was dealing with is in Savannah, Ga. He goes around and buys trade in's. From what I can see he has sold a number of them on EBay. He is in the past. Again, THANKS and have a Merry Christmas.

Dan, I think that is the same guy as 1Outboard on ebay? If it is, I spoke with the guy one time. He seemed ok on the phone. I have not had any bad interaction with him. Did you have a bad experience with him?

I'm pretty sure that is the same guy with Blackbird...If you look at his feedback on EBAY it mainly shows feedback from people he has bought from and not ones that he sold to.....I personally had a bad experience with him........stay away......far away! PM me if you want details......

I have a pair of twin 91 Yamaha 70's on my 18' Outrage. I can plane off one engine, but it has to be a lower pitched prop. I run 17" Stiletto's and cannot plane off of one engine. I keep a spare prop on board w/ a lower pitch in case one engine goes out.
I would seriously look into Yamahas new 70hp 4s, if your really want twins. They are a little bit heavier, I think 260lbs each, but the boat should handle the weight fine.
