I didn't realize you knew what was "right" better than the people who have elected to replace a failed engine in*their twin with a different engine.* I suggest you contact all these people and tell them that all their reasons for keeping their boat going are wrong and they should immediately*decommission their boat until such time as they can afford to replace both engines.Egregious wrote:

I will let the members of the GB owners board who have installed a different engine in their twin to replace a failed FL120 and who have posted about it on that forum*that you believe they are lying.Egregious wrote:In a pinch you gotta do what works, even if it isn't "right."*** I'm just giving you a hard time for posting hearsay.*
Eric---* I'm sure you realize this, but just to be clear, nobody that I'm aware of who's done this claims it's an ideal way to power a boat.* The people on the GB forum who've repowered one side in this way certainly don't.* But the choice for them was not to be able to use their boat because of the failed engine or replace the failed engine with a new, zero-time engine and continue to use and enjoy their boat.* The cost of replacing both engines*exceeded their boating budgets.* And they didn't want to get rid of their boat for another one for whatever personal reasons.* So the repower on one side made sense to them.nomadwilly wrote:

Eric--- I will pose your question to the GB owners group and see if anyone responds.* I've always been curious how they "balance" the 150 hp engine with the 120 hp engine.* If there is any meaningful reply I will post it here.nomadwilly wrote:

The single vs twins in a totally unwinnable argument except in the mind of each person defending whatever their choice is.* The statement that a single is "right" is as ignorant as the statement that twins are "right."ralphyost wrote:
The comment earlier hear about hookers and high heels was correct ....just because someone does it doesnt make it RIGHT.
Most oil tankers, bulk carriers, container ships, etc. are single engine.KJ wrote:
Would the size (displacement?)*dictate at which point a single engine*would no longer be practical
It is hard to believe that shipping companies risk millions of $$$ having only one engine in their freighters.* So, maybe it isn't a bad choice for us.nomadwilly wrote:It's a wash for most but for me I go many places that the loss of my single engine would be big trouble so for me it's a no-brain-er**** ...I'd have twins if I could afford it.

Syncing twins is done with the throttles and your ears (and your feet because you can feel it, too).* You simply nudge one throttle or the other until the thrumming is gone.* Some engines can have syncronizers installed on them which sync the engines automatically.* The out-of-sync conditon being talked about here is the matching of the vibrations--- harmonic and otherwise--- of the two engine so that you don't get them pulsing against each other.*This "sweet" spot occurs when both engines are running at exactly the same rpm.* Being out of sync a bit makes no difference to the engines, but as Eric says, the sound will drive you nuts.KJ wrote:
Could you hire an expert marine diesel mechanic to sync your twins (if you had them)? *
RickB can give you a*more meaningful response but there is little similarity between the maintenance and skilled labor available to keep the engine on a container ship, tanker, etc. running correctly and the world the engine in a recreational boat lives in.* As I understand it, the engine on many ships can be worked on (to a degree) while the engine is running.* Cylinders can be taken off-line and repaired or adjusted or whatever.* So "single engine"in the commerical world is a whole lot different then "single engine" in the toy boat world we live inmarkpierce wrote:

Seems to me this makes operating twins more interesting, helping to stay the boredom caused by knowing one can afford one engine to fail.Marin wrote:
