Classic sounding engine

[jaime66]

Got a LPW3 at moment but love the sound of the slow chug chug engines ,anyone swapped there engine for the classic sound ?

Swapping engines is for those with more money than sense. Usually it requires alteration of just about everything engine related .  Invariably the costs do not fall through to the boat  value either.

 

  Much easier to buy a boat with the sort of engine you want, and cheaper too.

Slow chug-chug means a physically much larger engine and for most boats, an engine room - 'cos they won't fit under a deck...

 

Just an idle thought  - how's about tuning the exhaust? being a 3 cylinder the exhaust sound is off-beat and that might be an achievable sound -

discuss....

Usually a LPW3 engine sits below the cabin floor of a trad, below the decking in a semi trad or a cruiser stern, not yet seen one in its dedicated engine 'ole (room) as a "chug chug" engine would be.

 

A "chug chug" engine would possibly be too physically large to put in direct place of the LPWS3 without a massive financial outlay, making the space a dedicated engine room, 3rd picture.

 

Cheaper to install one of these? https://www.popularmechanics.com/cars/a7923/the-rise-of-the-fake-engine-roar-11291754/

Would a Lister SR2 or SR3 be too big?

Not knowing the dimensions of a SR2 or 3 I cannot answer the question, but you still have to ditch the LPW and purchase a SR. Worth the cost for a likeable noise?

 

 

SR2 on Apollo Duck, £1500. https://engines.apolloduck.co.uk/boats/lister/sr-2

 

LPW's are water cooled, SR's air cooled.

Why would you want one of those.....complete waste of space and think of the brasso bills....?

The only thing is, if you have an engine like that you have to have the engine room doors open all the time

Keep your engine. 

A good big speaker in the right enclosure. Grunty amplifier, and suitable recordings,

You could have a Bolinder one day, a Kelvin the next.

All without the fumes and maintenance headaches.

How about splitting the manifold and routing 1 pot to Port and 2 pots to Stbd?  Stand on one side of the step to hear "chug - - chug - - chug", stand on t'other to hear "ch chug - ch chug - ch chug'

There is a beta JD3 somewhere on the cut that has done something a bit like this, silenced two and so just the one audible. It sounds interesting but not lovely.

 

To get that really lovely exhaust note I suspect one needs a slow revving engine, big pots to give a nice big heavy thump, and ideally a two cylinder engine to get the lovely slow revving uneven firing sound.

Also need exhaust smoke rings.
