How many knots

[Bobthebuilder447]

Hi can anyone tell me what sort of speed I should get from a diesel 7m humber with a d3-160 and dose the 160 stand for 160hp the guy tells me it's 130hp but I would have thought the 160 means 160hp help please.

He prob means 160 at the flywheel, less at the prop. Whatever, not too many knots. Early 30s maybe? Hopeless for an offshore 7m rig.

You are right about the D3 designations, a D3 that produces 130hp would be a D3-130, one that produces 160hp is a D3-160 etc.

There are loads of versions of the D3, going from 130hp to 220hp.

A 130hp in a 7m boat doesn't sound very exciting (or practical for load carrying/watersports).

Might give some ideas?

On top of the engine it says D3-160 so this must be a 160 I take it.

Unless it's a 130 with a 160 rocker cover on it!

A bit of sticker tuning. ;-) A car dealer pal of mine used to put 5 speed gear knobs on 4 speed Fords years ago, when putting them to auction. Imagine the buyer looking for fifth all the way home. :-)

Haha!

A mate had an '82 Escort 1.3L with "XR3 2.0 Turbo Petrol Injection" on the back.
The 2.0 was from a Granada, Turbo from a Porsche 924, Petrol Injection from an old Triumph and XR3 made from stick-on letters/numerals from our local hardware shop!

I used to have a humber 6.5 extreme (same as ocean pro) with a 120Hp (at the flywheel) mercruiser diesel, and I could get 35 knots at full tilt, I even touched 40 with a following tide.
It had a stainless prop, not sure how much difference that made.
