And it would still pump water just not the same volume as the other, but that was hooked up to a hose and not in the water. There is my 2 cents. I am glad to see you are moving along nicely. Reminds me of last winter for us. and yet mine never hit the water last summer lol. Good luck and I will post my pics soon so i will share my hardships.

I spoke with some one a few weeks ago and they said the pumps have to do with the mounting locations on the motor.I have one Gen 4 and one Gen 5.The mounting bracket for the 4 rotates the pump 180 degrees.So thats why the input hose mounts on top of one pump and bottom of other pump.I have not have time to look into this theory but I'm sure when I get my motors back next week and start hanging acessories I'll see the difference.And post some pics of your project.I really need to see that I'm not the only one this crazy.

Re: Winter Project

I received word from Roccard Marine that my engine dyno is scheduled for this Thursday.All my parts are in and should have assembly done by Tuesday.Mike from Roccard says my finale compression ratio will be set at 9.8 to 1.This seems a little high but he says with aluminum heads there will be no problem with running regular gas.What are your opinions out there in o.s.o. land?I also started asembling my gimbal rings and transoms tonight.What a pain in the a$$.I have all respect for you guys that do this day in and out with them mounted on the boats.Here are some pics from Roccard.

Thank Nordic95

Re: Winter Project

That make two of us.Mike seems to think they should turn around 625 -640 horse.I would be happy with 525 horse.The dyno will tell.

Re: Winter Project

Just got back from my dyno session.I have to admit that Mike from Roccard was a hell of a lot closer with his prediction then I was.Here are some pics and the dyno sheet from one of my engines.Tomorrow we will dyno the other and then back to my garage with both of them to start the assembly process.

Thanks Nordic95
