Favorite Type of Power for a Powerboat

[tom28571]

My choice is pretty well dictated by the kind of boat I prefer. Lightweight, trailerable, planing hull and economic to buy as well as use and maintain whether a skiff, runabout or cruising boat. Only one choice fits. The gas outboard.

The claim that inboards, whether gas or diesel, are more reliable than outboards is, I think, highly questionable.

I have made this claim myself from a personal observation. Of course your usage would dictate reliabilty. A daily driver is more reliable than a NASCAR or top fuel racer. With that said a local crabber tried using outboards for a few years. He had to replace the lower units on average about once a year. The bullet proof velvet drives lasted many, many years.

My experience regarding outboard versus inboard reliability matches Woodboat's, I think. In light lake-puttering outboards are fine, but I've had several of them crap out on me under high loads. Big inboard blocks, mounted farther forward, can be heavier and more solidly built than outboards (which must be as light as possible if they are to hang out two feet past the transom). Outboards are simply not built as heavily as inboards, in general, and so do not tend to hold up as well under bad conditions. (Take Merc's Disney test fleet, for instance: Average outboard life is only 12-18 months, running 8-10 hours a day; versus the many 30-year-old Crusaders worldwide that are still toiling happily away.)

Hey, I agree with both Woodboat and Marshmat but the instances you mention feature the uses where an inboard, particularly a diesel, are better choices. I remain convinced that the modern outboard when placed on a trailerable, lightweight and fast boat that is not used for shoving big heavy stuff around or running all day every day is the preferred choice. In other words, the average receational fisherman or pleasureboater, which is what I suspect most of us are.

My Yamaha 50 has had 6 seasons of such use and has had no, that's zero, issues of any kind and its use has extended well beyond lake puttering. My friends with inboards can not say that. This started out as a request for opinions and this is mine. Your mileage may vary. Good enough. Incidentally, my vote for outboards was not registered as the poll did not change after I voted. Voting irregularity or hanging chad?

I'm a fisherman and need to get into the shollow waters of florida so an outboard with a jack plate is the way to go for me.

If money was no object. Gas sterndrives it is.

Frankly if I had my druthers I go with Sail or oars. But if I have to pick an engine it would be diesel. I spent too many years in boating safety looking at fires and explosions. I honestly think gasoline doesn't belong on a boat. Radical? Ask the last guy who's boat blew up. Anyway diesels are reliable, durable, efficient, fewer parts to break, no ignition system to get wet. Modern diesels aren't as heavy as they used to be and have much better power/weight ratios, they have really good torque for swinging a big prop. The new direct injection diesels are clean and can use biodiesel fuels so they are good on the environment. But as I said at the beginning, I'm a purist, Sails or oars can get you there.
