Most engines that have roller lifters have a 5w-20,30 or 40 weight oil so they lubricate right away. I did not check to see if Marine engines have the same recommendation when running roller lifters.

Convention is non-synth straight 30w for initial engine break in (~10hrs) but I’d confirm with the builder. They should have a recommendation on weight to run afterwards as well (based on the clearances that they set).
Roller cam usually means it’ll be pretty tolerant of oil choice. A decent, reasonably priced option like rotella, delo or gtx would get my vote (for break-in). |

Also need to figure out what oil to run for the first change.... I know several Python owners are running rotella which is fine by me but I need to figure out if I should run anything different the first go round.

Priming it right before the first crank would be beat, but priming a few weeks earlier would be better than not priming at all. I would slowly move the crank while priming to make sure oil gets everywhere.

I understood the process but wondered how effective it was to do so if the motor still has a few weeks for the oil to run back into the pan. Curious what others think that obviously know more than me about rebuilds. :) |

It's not the oil pump that you are priming, it's the engine. By spinning the pump you force oil through all the passages so there's no dry time during startup. Curious if others here feel a newly rebuilt engine is lubed enough to not bother with priming, but I'd tend to do it. Basically you have a drill extension that matches the distributor end and spins the oil pump for a bit to build pressure and send oil all over the engine.
If you prime it and it sits a few weeks I don't see that as being a problem at all. |

Getting there.
So something I don't have a whole ton of knowledge on... Installting the Distributor+ Priming the oil pump. - I figured the pump needs to be primed before the first start but that leads me to a few questions.. I'm probably not going to put the motor in for another 2 weeks. I've still got to get the bildge area sorted out and I'm not home much for a bit. If I prime it now or soon does it matter if it sits for a few weeks? I'm trying to decide if I want to fill it with oil, prime it, and stab the distributor now or wait until i'm ready. I've also only installed one distributor in my entire life so making sure I get that right has been confusing. It would be nice to have the motor as buttoned up and ready to go as will fit through as we lower it in to reduce the amount I'm doing in the boat itself. |

Finally getting off my rear and getting started. Took a few days off during the kids spring break and I'll spend some of it on the boat.
Ordered all my external motor parts, ballast, bildge and all related goodies today. Plan is to have the motor in this month and ready to start by april fools day. |

Fun stuff now I'm going to get the bildge cleaned up and:
Replace all the hoses. (Fuel/Cooling/Etc) Add an underwater light New Bilge Pumps (one works and sounds terrible. New Ballast hoses and Pumps (set up for bags) Probably need to put some thought into a steering cable and re-pack of the shaft as well. |

Roller, it was clarified somewhere along the road but I don't think I mentioned it. I've got a new long block sitting in my warehouse. |

Did you ever figure out the direction your going with roller vs flat tappet? or is the jury still out until you tear apart the vented engine?

Well, someone had suggested that I take the v-drive and trans loose and scoot them back vs going to opposite direction with the motor. But, I believe that was under the impression all the accessories were still hanging off the front of the motor.

Don't know how you could do it any other way unless you were able to remove the engine and trans as a unit? Do you think it's easier to separate the engine from the trans or the vdrive from the trans? Not alot of wiggle room there anyway and the BB iron I'll bet even less.

Drug the boat to the office today. Going to use the forklift this evening and get the motor out. I'd really like to leave the trans and v-drive intact. Since all of the accesories are off the front of the motor and I've actually got a little wiggle room to do so any reason I don't want to do it that way?

For heavy duty marine applications you must use a screen and THEN flex seal |

I've got it down to the long block in the boat right now. Hoping to get it out one night this week at a buddies shop. I think I want to seperate the motor from the trans and leave the trans/v-drive intact. I should have enough room to slide the motor back a little. It's tight quarters back there when the motor is fully dressed but not horrible with all of the stuff that hangs off of it missing.

That can be fixed with a quick trip to your local Home Depot.

Always interesting to see the sheer power of that rotating mass of metal! Bending one of those is no easy task.
Yup, some Lucas, JB Weld, and straighten it out and you'll be good to go! |

Haha, it came off right after.... It was actually only connected so we could raise the hatch and pull the pin. I just got button happy and away it went. Batteries are actually sitting on the bench on a trickle charger. |
