Hi guys have just taken proud owner ship of a p5 dynastart thats ment to been recond 2 years ago which looks to be right as the paint looks pretty good and has 100psi of compression.
I have just a few things i am unsure about as i am more at home with 2 stroke outboards
1 Is the dipstick on the side of the engine for the gearbox?
2. what oil does the gearbox need
3. Is the crank drain near the engine mount by the fly wheel
I have tryed to start the engine but only got it going once just about most i can get it to do now is fire but not run i think i have a carb/fuel problem or is there a techneique to starting the p5
She is powering my 18ft grp fishing boat sim to a plymouth pilot will this push it along ok on the sea? at what sort of speed?
Ps have cuaght the stuart turner bug!!! |

Gr8 that you too have the Stuart bug. You will have to work at the relationship though! That engine should be alright for the boat. We had one in an H28 yacht. To answer your questions: (are all the other guys offline?).
1, Yep that is the dipstick for the reverse box.
2. Use straight 30 sae. Takes about a pint. Don't overfill -the mag can overheat because the box does.
3. Yep the drain is on one of the engine mounts -port side I think.
To get the best, you need to ensure that there is spark when you need it and fuel. Remember to use 20cc of 30 sae to one litre of fuel. You can use two stroke oil but people seem to shy away from it.The spark has to come at the right time so check and recheck the timing and see that the mag coupling is not slipping. Replace the sparking plug and keep the spark gap .018 -.020". My 1951 (I think) P5 will usually start by flipping the flywheel hot or cold unless people are watching. It has the original cast iron piston. If the spark is even a little out, there is nobody home. If you have an impulse mag, they are a different timing technique. Pity you have Dynastart, you are missing out on so much. That technique of holding your tongue in the right place and giving a smart upward flick on the crank. So cooool.... |
