Bit of a stupid question...

As the title says, its a bit of a stupid question...

Without knowing the kind of a boat, how heavy on the fuel would a 3.0l 4 cylinder 135hp mercruiser inboard engine be as aposed to a 90hp 4 stroke honda outboard?

Does the 135hp inboard give similar consumption to a 135hp outboard?

Been looking at new boats and wondering if the inboard is gona give hellish consumption compared to a 4 stroke outboard...

Cheers

Hi Gary,
Unless the inboard is a diesel, I can see little point in going for an inboard.
Firstly you lose space in the boat. Secondly, if you dont like the engine or need to change it, it will be much easier with an outboard.
Nick.

the price of boat configured to take an inboard, the inboard itself with leg compared to the price of a boat and outboard

what you would lose if you had an inboard...seats or usable space needs to be considered

as mentioned below the amount of room you would lose on a small boat would probably be substantial

the weight of the two options might be a major consideration as well

and then the resale, would others want a small boat with a petrol inboard

outboards are well proven, petrol inboards can be an expensive pain

personally i would stay outboard and would go inboard on a larger boat to get a diesel

i have a honda 90 4 stroke outboard, love engine, very economical and quiet but if the boat would take it i would go for the suz 140 personally if 4 stroke was denf required

It is my understanding that an inboard is more economic than an outboard for the same HP

You can get an imported American Bayliner/ bowrider type thingy new for under 12k and these all seem to be fitted with inboard petrols, good value for money methinks (closet hard boat owner )

Have you seen the shit those things are made of?

There's a web page I saw(that I can't find right now) showing structural damage from hurricanes and what these so called 'composite hulls' are made of.

Essentially one layer of CSM, 1 layer of woven roving and a shitload of FILLER.

I'll post the link when I find it.

Dunno where you got that idea from Nos I always thought they were paper mache!! There are some horror stories, but they do seem to last, and if your only going out for the day and mainly inshore probably would be all right, im not talking about a circumnavigation here! The drives and engines seem to have been around for a while though, so I assume the majority of problems have been ironed out. I know of some horror stories from apprentices at sunseeker too though, not posting them cos someone will sue my ass!
