Default Repower Suggestions - Twins or Single?

I have twin 2001 115 hp Johnsons on my 23 cuddy cabin. One engine has blow powerhead so I'm thinking about repowering with either twin 115s again or a single 250hp. How hard/expensive is it to cap old mounting holes in transom and drop on a new single 250? Is it worth it or should I just stick with the twins? Thanks in advance for your advice.

There is no yes/no answer to this, twins are nice, single is cheaper, twins have more torque, single is faster, fixing the old holes is not an issue, buy what you will be happy with.

True - a single 250hp would be cheaper to buy, faster, cheaper to run, and weigh less, but I'm worried about the cost of the transformation of going from twins to single - namely filling in transom holes, removing the old twin controls, changing battery and fuel lines to single. How much is all that work gonna cost me in a boatyard down here in South Florida?

What exactly in the original post inferred that he abused it or doesnt know how to take care of it? 2001 motors anything can happen. Why are you always such a tool and have to be so condescending to everyone? Why have you not learned correct syntax and punctuation? You obviously have considerable knowledge and have much to offer to many on this forum, but your delivery leaves something to be desired, almost every time. I realize you also have lived in a different culture for quite a while but damn. Dont be such a troll and people will respect your input, knowledge and credibility so much more, unless you are that bored and it was your intent all along to troll.

Oh! WAIT. !!!! I for GOT caps. !!!!!!! !!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!
! and Ex!clamation! MARKS!!!!!!!!!!!!!!

Filling the holes is not a problem, it will cost extra, and it's not quite as simple as "just do it" price is not the be all to end all, neither is a few miles per hour faster.

My first suggestion would be to check what maximum HP your boat is rated for. If you opt for a single engine the cost for a 300 hp motor isn't substantially more than a 250 hp and that might be worth considering. Secondly pay attention to weight of your current engines vs. the weight of new twins or a new single motor. When you boat was built in 2001 four stroke motors were just becoming available. You might find that twin four strokes are too heavy for your boat which would indicate that a single engine would be preferred. And finally I would suggest that you not worry about changing controls, battery cables, etc. All that stuff is 20 years old and should be replaced anyway.

For me this would be more of a question of what I would be comfortable with. For me it would be a single, easy answer. Controls wouldn’t be a real thought. Motors of today and controls of yesterday usually don’t mix. Reliability of today’s four stokes takes the need for twins if you lose a motor off the table “for me”. Add that together with cheaper and easier to maintain. For me no brainer

Your cheapest option might be to get the blown 115 rebuilt.

How long do you plan on owning the Boat? If you are going to sell in the next few years Rebuild what you have.

The cost to switch to a single is much less then the increased cost of the twin repower, increased maintenance, and increased operating costs.

The single 250 will be cheaper in the long run by a great margin.

It is similar to asking "should I vote for a democrat or a republican in the next election".

Answers may vary.

It’s all about your piece of mind and what you are comfortable with. BTW, Evinrude still sells the Gen 1 ETEC and Mercury (I believe) still sells the Optimax motors in case you want to stay with lightweight twins.

I agree with John185 (although I agree with John 3:16 even more) that engines of today pretty much mitigate the need for two engines “in case one of them ...” but if you go far offshore, there is still peace of mind in knowing you have an extra engine. Sometimes, the failure of an engine to operate isn’t necessarily the reliability/mechanics of the engine itself. So here’s yet one more humble opinion… if you go offshore lean toward the twins but if you don’t do it that much then go with the single 250.

What's the clearance between the top of your engine and the first obstruction when the engine is up? Just making sure the obvious witch will become crystal clear after installation doesn't occur.

as a previous poster stated. Check the weights but also the hieght.

you don't tell us anything about you or how you use your boat so it's not possible to answer.

Haven’t you heard that quads are the current way to go? If you put quad Yamaha 70s on that thing you would be the man.
