4.3 Litre Mercruiser Stern Drive (new)

[madman1]

A good mate of mine is contemplating purchasing a new boat with a 190Hp stern drive merc as a demo.

Has anyone had any feedback re the engine either good or bad as neither he nor I have heard anything about them as we are both Yammie and Etec boys.

All feed back would be greatly appreciated


Cheers

I have this motor in my boat & haven't had any issues with it..They are carbie not fuel injected but been around for year ..

[madman1]

Good to hear.

What is the fuel efficiency like and what kind of boat are you fishing from.

Hi Madman,

THis is not exactly the answer you want, but I have the 220HP fuel injected Mercruiser 4.3L V6 in a Whittley Cruiser 660 (nearly 2 tonnes) and it uses LESS fuel than my previous boat which was a 5.2metre Swiftcraft Sea Hawk MkII, with a 90HP Evinrude 2 stroke. MUCH LESS!
I would imagine that the carby 190HP version would not be quite as fuel efficient, but still very good.

I have 2 of them in a 26 caribbean and they have been fantastic at 3250 revs i cruise at 26 knots and chew approx 40 litres an hour for both engines.Mine are 205 hp each.At full throttle i do 40 knots at 4600 revs and would be scared to know how much they chew then.

Thats a good speed for 3250rpm Bastard.

The one I sold to a customer had very healthy 470's in it and we used to do 20 knots at 3000rpm. So theres a fair bit more torque with the V6's then.

Madman, they are a good engine.

Cheers

My mates got a 25 berty cruiser version with 470s and no antifoul it cruises at 23 knots and does 30 full throttle,they never made a 26 caribbean with 470s so its hard to compare,but i to have no antifoul and i swing 21 inch mirage props,one of these is counter rotating.The most accurate fuel run i have done is i left kooringal at the gutter bar and drove to gold coast boat club i didnt come off the plane the whole way and i used 70 litres of fuel,we were out for 10 days so the boat was heavily loaded but this doesnt seem to make any difference in fuel consumption or speed.cheers

Mark, I have the 220 pushing the 6.5 whittley sea legend. She was guzzling the juice till I decided to back off the revs. She goes so smooth that you don't realise how fast you are going hence the extra fuel.

I only motor at 3000 revs now which still gives me 28-30knots in a kind sea and I'll use about 100 litres from nudgee to shallow tempest and back. At 3500 you can half that again. It's not worth it for the extra 5 knots.
