Twin Etec 115's for a 23'?

[Islandtrader]

This is just my own opinion.

Why do you need twins?

Double the money double the service double the trouble.

I know every one says safety factor...but do you know that people who cruise around the world in 40 foot blue water boats only have one engine.

Normally twins or triples are for boats that need horsepower that they can't get out of a single.

I would say in the "old" days when out boards weren't that reliable the twin thing had a safety factor, now a days I think that argument is nil.

This just my take on the whole thing.

I did think a lot about single vs. twin. Should I get 230hp in 2 motors or 225hp in one motor? And I think I want 2, here are some reasons I want to consider twins:

1) Initial purchasing cost is not that much more in the specific Etec case (not sure of other makes).

2) I've had my 1994 twins for 16 years. I think I would have replaced a single engine by now. So I am really getting my moneys worth. I've swapped parts from one to the other to troubleshoot over the years, this helps with maintenance costs and I'm deferring my initial costs so in my opinion there is some savings here.

3) This is a personal one but I use the boat exclusively in the Florida Keys where it is shallow. A single engine would reduce my draft by probably more that 6" because it would be in the middle of the V compared to twins hanging up off the bottom of the V.

4) Maneuverability in marinas and canal systems with twins is much easier.

5) Counter-rotating improves the ride in rough water because the single prop will walk the transom slightly to a side as the hull comes out of the water.

The cons I see in the twins are the higher maintenance costs and the extra weight.

I'm not sure the fuel for 1 motor is more than 2 motors? In the performance reports I read on the Etecs both are real close to 3 mpg (twin 115's vs. a single 225). You have 8 smaller cylinders being fed fuel compared to 6 larger cylinders... More drag with 2 engines... this is a hard one.

This is what makes this a great forum, and I appreciate all the input!!!

About my prop make, I got them from the OMC dealer when my engines were bought and I think they are Vipers circa 1994. The dealer had put 15X21's on to start with but I could not plane on 1. It was a luxury to try the props until I liked specific ones.

Yes sir, I liked the picture of your boat with the old RR bridge/Overseas Highway in the background.

[McGillicuddy]

Yes, ditto on DonV's comment. Nice pics of a really ideal fishing rig. Looks like you're pretty good at R & R, too. Really like those Charger colors...

Like Island Trader, I would typically favor a modern single over twins but you make some interesting points based on your shallow water and maneuverability needs. Like the part swapping bit, too.

I hope you'll post some performance #'s when you get re-powered.

That never crossed my mind, however I must admit those "powder blue jerseys" and especially the lightning bolts on the helmets were my favorite football uniforms when I was a kid....a long, long time ago, oh yeah, for those too young to remember back in the AFL days.

Go with twins. Compare the fuel consumption of the 115 and 130 Etecs.
The comment about 40' bluewater boats having only one engine is disingenous: Most also have sails. Those that don't, have diesels.

Learn how to spell a big word before you use it. I was just giving my opinion so I hardly think I was being disingenuous.

Sorry I should have said the Blue water power boats...still only one engine and being a diesel has no bearing on being reliable...longevity yes.

Pardon my poor typing skills. I didn't use the word in a pejorative sense.

In addition to "(1)lacking in candor, deliberately misleading;" my 1877 Webster's defines Disingenuous as also meaning "(2)unaware or uninformed; naive; ignorant; (3)to speak from ignorance; (4) to omit pertinent information, either willfully or inadvertently"

It was the last meaning I intended. If I offended you, please forgive me, I certainly did not mean to do so.

I will give an answer on each point, I am familar with the keys and the boat as I had a 23 Sceptre that I switched from twin 150 Mercs to a V8 Rude 275.

1. check the 130's I don't think you would be happy in any seas with driveability, that hull is a high performance hull and it does like HP - I bet you not will plane a 23 w/115HP. I'm surprised you can with a 140 and 19" props

2. This will not be like your 140's - you can't work on these things - they just aren't as simple as the old days - honest. - It was easy - carbs, spark,fuel pump no more - 3 fuel pumps, modules, wires, hoses everywhere LOL and I only have EFI not DFI.
- motors depreciate, your hull will not - 2 motors depreciating vs 1

3. I think negligable - a 225 or 250 doesn't weigh 800lbs - and you have trim, my hull bumps first, when I'm real skinny

4 agreed, twins are so sweet in close - but you could get the hang of it, not that bad

5 Disagree, I had twins - the single rode like I bought a new boat, hull was much more responsive to trim and rode higher on the chines - it felt nimble like a 20 you really could drive it in seas - it was an amazing difference

6. The maintainence will be minimal for good while, other than filters and cables - you will use more oil and fuel. The 2 smaller motors will still use more than 1 of equal HP.

In closing, these new motors are highly reliable- in most cases, everything breaks but they are a far cry from 20 yrs ago - especially the Etec's. With a single I truely think you could see almost 4mpg at cruise as I have seen reported for the V6.

The biggest factor after 16 yrs - we didn't have SEA TOW for $150 a yr, honest they come right out and drag your azz home faster than 1 motor would run you. So call them, fish some, have a beer they will be there before you know it. I used them for the first time this year, I had them and it still was kinda scary the first time - no worries anymore. The first time they had to come 20mi up Tampa Bay and thats how long it took him - I fished.

Great boat always wondered way more people didn't buy them, although they came late but I thought it was perfect, but CC's were the rage.

good luck whatever you decide, it can't be a bad decision
