Another Pacific 22 question!

Does anybody know anything of the history, or any other details relating to this: http://www.boatsandoutboards.co.uk/view/F49158/ ? It looks like a Mk.1. I wasn't aware that there were any jet Mk.1's or is this likely to be a retro fit jobby?

Cheers all

Andy

It is a MKI and is, as far as i know, a factory built boat. There are loads of MKI variants out there such as this but i believe most are 1 off builds so unlike the MoD standard spec boats, are rare to see second hand.

Speak to Neville about it if you need any real details - im almost positive that he sold it to the current owner.

jet pacific

Andy,

I don't know first hand but don't believe that Halmatic made any Jet mk1s.
Saw a converted one a few years ago when I was looking to buy one for a customer- pete7 commented on this a few weeks ago.

Development mule for the mark II with Jet installation perhaps. Vospower jets from Vospers / Halmatic.

240hp at 3500rpm - sounds a bit like the Yanmar fitted in the Navy mkIIs?

Not thinking of changing yours already?

Hi Duncan, no I'm not thinking of changing mine yet, but was talking to someone this afternoon who'd seen this ad. Agreed, it's got Yanmar written all over it, but I seem to remember someone mentioned on here about a Mk.1 that had been converted to jet and turned into bit of a pig. Hope you're keeping well.

That was Pete7 - I also looked at when it was offered - it was a bit of a woofer - but probably cleaned up OK for someone with deep pockets!

Yes, keeping well at the moment - just running things down in the run up to Christmas.

If you take a look at the hull design, youll notice that it is considerably different to an outdrive MKI.

The Chine is considerably lower and more defined than the MoD boats and towards the stern, the upper 'cluster' of spray rails is missing.

I beleve the one that Pete7 mentioned was a DIY job and was basically a jet MoD P22 which handled poorly as the hull had not been modified to suit the drive change.

I have also seen another jet P22 once that was again almost certainly a factory built boat and featured the same hull shape as the one in question although it had a CAT 325 in it as opposed to the Yanmar which this one once had.

Im pretty sure that if youve got the money, Halmatic will build exactly what you want from scratch which is why many of their boats are one off's which leads people to think they are conversions!

Looks like a good project to me! Its much improved compared to the MoD boats - GRP engine box, more storage, more fuel capacity etc etc

Problem with this one is no engine or tubes so how do you know when you buy it that the jet is going to work properly and not turn out to be a dog ? can't say that I was impressed by the last jet P22 I drove. It had as much control as a dodgem car at a fare ground.

Shame because the hull looks in good condition and that trailer won't have been cheap.

Not sure if it would be a Yanmar, We have a MK1 P22 at work at the min, im just doing the first Yanmar fit (as far as i know!). But i have to do it in kit form so when the Mk1's come in for refit the Yanmar will go in to replace the old Mermaid with ease!!!!
I tested the boat with a Mermaid in it to see how quick it was etc but it only did 28knts with 2 people does that sound about right???

Will let you all know how well it went with the Yanmar in it.

Thats a very speed for a standard Mermaid. Any chance of some photos of the switch to Yamaha?

I went and looked at this boat when it was for a sale at Babcocks in Southampton almost a year ago.

It is a standard Mk1 hull at the front that as had the rear portion changed to maintain the size of the planing foot, this jet is fitted through the hull by cutting a hole for the water intake. The loss of this area has to be made up or the boat will not plan. Hence the change in rear design.

On the boat that Pete7 looked at the intake was rearwards of the transom so no need to change the hull shape.

The engine box on this boat was huge and although it had no engine I got the impression it had had a big lump like a Cat or Sabre, having said that 3500 rpm is high speed for an older style diesel.

Being a 96 boat it has had 6 or 7 years service In the Navy which is not long, most are going for sale after 10 years. Maybe that says something about its abilities or maybe the Navy had learn all they needed to know, bare in mind that the mk2 have jets so this boat cannot have been a complete disaster.

I think it is over priced and wouldn’t pay more than £5K for it, at this price it would make an interesting project. Des
