don't think any of us has a dry clean bilge, still it was re-assuring to see a two year old Ribtec inboard with more oil than mine last year.

Recon you rev counter is out, since the speed is about right.

Thanks Pete,
I didnt expect the bilges to stay clean for long, but a bit longer than they have! I only cleaned them because it was my new toy and I was feeling all keen!
I could borrow a hand held tacho and check the RPM I suppose, then again if its working leave it alone!!

Yep, mine doesn't read properly either, did quite like the look of one of these, but can never remember to take me micrometer down to the boat to find out what size the injector pipes are.

i did tell you i thought that the mounting looked dodgy!

i would check with a tacho aswell. if it is out a bit, try replacing that pressure maintaining valve on the side of fuel pump that i pointed out to you. i remember having problems bleeding it with high air pressure in the pump and that was about a year ago. that would drop the w.o.t. down a bit.

Pac 22

Hi All
Just a quick update whilst we are on the pac subject, managed to cut the hole out for the fwd hatch without cutting into the cross bearer, couldnt believe the amount of space in there,being a short a*** managed to get in there and clean it all out. Just sorting a minor snag with the fuel supply and about to fit the second set of batteries. Hope to go for a blast next week end. Where are you all stowing your liferafts.
Will give speed and RPM etc. when tacho sorted.
Paul

Liferaft on board a bloody great tug at the moment but Ian and I are using the A frame to store the raft out of the way. If you don't need the space up the very front perhaps a small divers bottle rack would make a frame to hold on to whilst working up the sharp end and secure the raft to as an alternative ?

If you've got a Blue Line model VDO tacho on the P22, it may just be set incorrectly. On the rear of it there is a small plastic slot head scew (if i remember correctly) and turning this one way or another will adjust the reading of the needle.

So, if you test the RPM with a seperate device at the engine, you can then calibrate the actual gauge to read correctly.

If its out then, its the engine that needs 'fiddling' with.

Cheers
