If you're envisioning a family fun boat, as opposed to a bachelor's toy, I would SUGGEST the I/O version of the Q.īut either way, you'll need a plastic surgeon to wipe the grin off your face.Ĭlick to expand.I was referring to the overall cost of the boat, not the cost of an upgrade from a different model. Both are good solid engines that will last a long time if you take care of them. There's nothing wrong with either, mind you. The difference is that they have an automotive weight reciprocating assembly inside, which carries MUCH more inertia than the ultralight outboard assemblies. However, the inboards are fundamentally automotive cores with a marine life support system, which means they more amenable to poking along at 3000rpm, which will STILL get you a nice cruising speed. If you get the 320hp inboard it WON'T be as fast as the 350hp outboard, and that's not just a 30hp difference issue. If you're buying a Q, the price of gas is an ANNOYANCE, not a dealbreaker. No disrespect intended, but lets face it. Oh sure, you can take your boat to Seven Marine LLC and have them re-certify it, but I'm pretty sure that turns your Bennington warranty into a cocktail napkin. Unfortunately, the highest rating that Bennington gives to their Outboard boats is 350. In THEORY you could go with an aftermarket motor like the Seven Marine 557, which is a supercharged Caddy CTS-V engine with over 550hp. Frankly a 25" Tri-Toon with a 250hp outboard is going to be a hard "overall" combo to beat.īut, having ridden/driven a 350hp Yamaha Q. The 377" Mercruiser is a bit of an under-the-radar monster with forced induction.īut, you mentioned gas consumption, so. On the other hand, you can buy an aftermarket supercharger for your inboard. Would a 350hp outboard be faster than a 425hp inboard? My marina's owner says so, and although I've not seen any good match-up to confirm this, he's been running that marina for decades. In terms of the stock Bennington line, outboards are faster than inboards when you try to compare apples to apples.
