Re-engine Pacific 22

I am considering a new engine for my Halmatic Pacific, which is currently powered by a Mermaid turbo four. Front runner is Ford's PT32 but it would be great to have some other ideas to throw into the pot.........

Hi Si and welcome to the forum. I have an oppo who deals with pre-loved Perkins if you are ever inclined in that direction. If so drop me a pm and I'll put you in touch.

Have you got the standard RN 140 hp version? is there anything wrong with it other than it's a little under powered? The easiest change would be to have Mermaid rebuild it for 180 or 200 hp. That should give you another 15 years.

You also know that it works well in a P22 rather than say the 165hp Yamaha 4 cyl or one of the inline 6 toyota type engines, as it the revs suit the stern drive and prop options and weight etc.

If you haven't dealt with Mermaid they are a family business with lots of experience of these engines and well worth having a chat with them.

Thanks Ian for the welcome and also for the suggestion - I was in fact thinking of losing a bit more weight (which my wife tells me is much needed!)

Thanks Pete, It was Mermaid who suggested the Ford engine...I agree they are certainly a great company to deal with.

Dread to think how much a new Ford 32 engine is, must be the thick end of 15k without fitting hence the suggestion of a re-build.

BTW in the stern power manual is a calculation for the max power the drive is rated for. From memory it's something like 175 hp at 2600 revs. The good news is unlike mercruiser or volvo the exhaust doesn't go through the drive and the water pick up is separate.

Why is this important? well your stern drive has something like 3 gallons of oil sloshing (splash box) around helping to keep it cool whilst the merc and volvo have oil which can't mix between the top unit and the lower unit. Does your drive get warm? worth checking after a long run, even in the UK mine would be warm after a run which was really surprising.

Something to think about anyway.

Pete

There is an Artic 22 based in Poole as a demo boat with the new Ford Puma engine in it. It looks and goes very well!

I had heard of the Poole boat, which Mermaid can demo. Thought it was a Pacific and not an Artic.
Pete - very useful point, thanks.

I second comments about Mermaid - had dealings with them in my old job and a very helpful bunch!

Yanmar 4LH is the standard engine replacement for the Mermaid in the navy Ribs.
