If you’re buying used as opposed to new, you’ll have some additional things to keep in mind such as the condition of the powerplant – be it an inboard or outboard. Diesels do tend to have better efficiency, however, so the have an edge when considering operational costs. Note also that diesel inboards cost significantly more than gasoline inboards. In some cases outboards will be less expensive but in others, inboards may cost less. This factor will depend to a great degree on what type of boat you’re looking at, and the types of engines the manufacturer builds with. Diesel engines still hold a reliability (and longevity) edge, but when it comes to gasoline inboards, their reliability is very similar to that of the outboards. Today’s outboards are, however, far more reliable than they were just a decade or two ago. There was a time when inboard engines and diesels in particular held a hands-down advantage over outboards when it comes to reliability. If you plan to keep your boat for years on end or if you’re buying used, it’s also important to remember that in the case of a complete engine failure it’s much easier to repower a boat with a fresh outboard engine than it is to replace an inboard. Since owner maintenance has been whittled down to just a few simple tasks, it’s more or less become a wash in the inboard versus outboard debate. But beyond that, you’ll need to call in a pro. Freshwater flushes, oil changes, and changing fuel filters can all still be done by any competent DIY boater. In the modern age, most boat owners will be taking care of the most basic maintenance chores, only. Modern computer-controlled engines of all types are complex enough that most boat owners address only the simplest of chores. Inboard engines coupled with stern drives also provides the ability to trim the drive unit up, but the only time that inboards are really ideal in shallow draft situations is when you have jet drives.įor a complete rundown on the different types of drive systems available with inboard engines and the strengths and weaknesses of each, see Inboard Drive Comparison: Stern Drive, Forward Drive, and Jet Drive. If you plan to go gunk-holing or would like to drive the boat up on a beach, outboard are great since you can kick up the engine. And in the 30 to 50 foot range there’s generally a mix. Below 30 or so feet, particularly if you have draft limitations or expect to keep the boat on a trailer, outboards have long been the favored choice. With modern monster-sized motors like the Mercury Marine Verado V-12 600-hp outboard, builders are placing outboards on larger and larger boats. Up to now, from 40 feet and up inboards have been the usual choice. The things I like most are the increased range and economy the diesel gives & availibility of diesel in my cruising area of west Cork, and oh yeah as you can see spending a lot of time under the hood working on the engine.Will you opt for an inboard, or go the outboard route?

But I am really happy with this boat and engine setup, I am lucky that I am able to carry out all my own work as otherwise this would have have been an even costlier year had I had to pay for all this work. Now reading this post people might think that I would say outboards everytime after my experience with the Volvo D6. My first year with the boat I had to replace 1 of the hydraulic trim hoses (this was my 1st experience with Volvo prices) since that time I have carried out the following 4 new steering hoses,2nd trim hose,2 new steering rams (this year) and then to top it all off I had to replace my sump this year as corrosion had caused a pin hole.Īfter removing the engine changing the sump and refitting the engine with a new sump fitted I thought that was the end of it for a while, but no on start up I discovered I had a leak in my power steering pump, new pump ordered and fitted. supercharged / turbocharged coupled to a DPR outdrive. This brings me to my present boat which I have owned now with 4 years the boat in question is an Exalibur 8.7 mt fitted with a Volvo D6 350 hp. My experience with inboards has been with Volvos, first one I only kept for 2 seasons as I got an offer to good to refuse. I never had any problems with any of my outboards but then again I used to move the boats on fairly often ,seemingly I got off lightly with my Evinrude 90hp. Mariner 60 hp 2st ,Suziki 70hp 4st, Evinrude 90hp ficht, Evinrude 225 ficht & Suzuki 250 hp 4 st. I have owned 7 boats throughout my boating career,5 with outboard engines namely
