The boat we were looking at has twin Mercruiser 4.5L petrols with sterndrives.
OMFG. How unsalable is that going to be on the Thames!!
Reckon around 2 gallons per hour on the River, per engine.
A single engined Diesel would be under 1 gallon per hour.
And on that note dont let the broker suck you in with tales of blinding fuel economy and ease of refueling petrol boats waterside. Its usually a load of cock and bull. Brokers prey on first time buyers to try and offload their unsold petrol boat stock onto them. You may manage fine on the non tidal river, after all petrol stations are to be found in most towns nowadays, but start to get more adventurous and have visions of heading onto the salty stuff and petrol avaliability becomes much more of an issue.
It would perhaps be more fair to name individual brokers of which you have enjoyed such treatment, rather than tarnish some decent blokes with the same horrid brush.
In defence of the local Thames brokers, I have always received fair advice, even if it wasn't what I wanted to hear!
Imagine how you would feel if somebody who didn't know you posted a threat about Sports Boat owners all being Tw@ts or similar. Clearly the decent brokers, of which there are many along the Thames, will be very unhappy, just like you would.
If you want reviews and fuel consumption figures on a lot of the american boats take a look at http://www.boattest.com/ (the site has nothing to do with me) but as I have a Bayliner 285 there are some extensive tests on there and full consumption figures at all speeds/rpm.
Also if you moor at MDL marinas you get 21p off per litre of the published fuel prices, just some info for you.....
Call some of the marine engineers for maintenance costs for particular engines if you don't want to do work yourself. At least it will give you an idea for your budgeting.
Lastly, not all brokers are bad the one we brought from was truley fantastic.
Here's some pics of our inappropriate petrol guzzling boat on the Thames![]()
I would advise you to buy a boat that is suitable for the environment it will be used in. The sports boat with stern-drives is happy in the salty stuff or down the estuary operating at its designed cruising speed.
Chugging along the non-tidal river at 8kmh will require constant steering correction as the vortex shedding occurs first on one quarter and then the other. Look at the wash created by a planning hull travelling at slow speed and watch how they constantly zig-zag despite the helmsman’s best efforts. I find this very frustrating/irritating and much prefer cruising at slow speeds in a boat with a displacement hull and a regular propeller shaft.
So, if you intend to make sea passages the sports boat is an option. If you propose to spend most of your time cruising up and down the Thames with the occasional trip to London I would not recommend anything with a stern drive.

Yep, we tried that, but the OP doesn't seem to want to listen
Seriously, the more I think about it, the more I think how absolutely horrible a twin V8 Sterndrive sports boat is going to be above Teddington.
Wrong hull, wrong engines, wrong propulsion...as the nice man said 'There are a lot of twin petrol engined boats for sale up the Thames'

@ CX54WEK -Yes you do get 21p off both petrol and diesel
@ Neale - Yes, you are correct sorry I forgot to mention it would be US gallons.
@ inlandnewbie - We also have a duo prop which cuts out the zigzag.

I am not aware of a merc 4,5 litre petrol. There are smaller I4's of around 3 litres, and V6's at just over 4 litres, the V8's are 5, 5.7 and bigger.
Did he go on to mention that there are even more diesel boats for sale?Wrong hull, wrong engines, wrong propulsion...as the nice man said 'There are a lot of twin petrol engined boats for sale up the Thames'
