Do you guys like to prime oil or do anything special before the first start up of the season? I don't think this motor has ran since September. Probably being over cautious but I thought I'd ask.

^^^ Kind of surprised that this one didn't get any pings. Now I'm thinking and researching hard on oil prelube/priming systems. Everything from http://www.petersonfluidsys.com/filter_mount.html to a harbor freight drill powered pump that one could easily connect to the oil filter out hose to electric systems. Looked at hand pumps as well. I've always cringed a little starting a motor after it's been sitting for a couple of months but now I think I'd like to avoid that.

So the question will be how to incorporate a prelube system that can be easily used. I would like something I could use before every time we go out. An electric pump plumbed into the oil lines would be nice but the Peterson prime able filter mount looks easy, but a charged up cordless drill is another thing to add to the preflight check list....

I'm going to go insane if I can't get this engine in the boat and put it in the water soon

It better get warm soon cause your "snowball" keeps rollin getting bigger and bigger! LOL

Pre lubing the oil is great, might as well convert to dry sump also! But where do you stop? I think our valvtrain wears out well before anything the pre lube system prolongs.....

Cool topic though!

Yea that's just it, keep falling further down the rabbit hole. No doubt the valve train will get beat up anyways. I would just like to know there's something on the cylinder walls more than anything before I go to crank it over after sitting for a while. Not sure a pre luber would really help there though?

I'm bored so I took a couple of shots comparing the bravo lower to the scx lower. The scx lower looked massive to me but after laying it right next to the bravo lower I guess it's not that much bigger, but still bigger, and heavier! It also was noticeable that it took more effort to spin the shaft by hand vs the bravo, but I guess that's just reliability.

The scx bullet is 5.35" and the bravo is 4.78" according to my measurements taken at the back of the bullet.

This is where I think a lot of the issues come up with the scx lower, the difference of bullet diameter to prop hub diameter

It surprised me that the skeg isn't streamlined more right out of the box, but I guess that's so they can sell a blueprinted version

I don't know why pictures get spun 90 degrees sometimes

You don't sharpen the trailing edge

Details would be awesome...

No, a prelube pump / accumulator won't do anything for you in regard to the cylinder walls. All it will do is pressurize the oil journals. That said, I would not be at all concerned about the cylinder walls being lubed at startup.

I've never done anything other than just start it up after sitting the winter. Same with my hot rods.

However, if you are REALLY concerned about it, you could pull the fuel pump fuse(s) and crank the engine over until you see some pressure on the gauge. Poor man's pre-luber.
