are these parts for 1980's P45? Or later P45R type Picco's?

 

[NITROSNIFER]

The measurements tell me the are P45 parts and the porting in the sleeves does not match EXR version. Still a good stash of parts if you have the P45 Picco's

I agree, these are for pre exr DISC VALVE P45's

yeah, you are correct. Paying closer attention, the sleeves exhibit the older style porting. But definitely valuable parts if you own the older (1980's) Picco P45 marine engines. Only thing you would need are extra new rods (ie. RPM rods)

This is my 45 and they don’t fit

that’s interesting, because that looks to be a 1980’s P45. Maybe there were different versions during those years? Possibly late 1980’s? Or early 1990’s?

 

[Mike Hughes]

Those ports do not match the 95-99 piccos.

Are you referring to the blue head era

 

[jim kapanowski]

I was thinking maybe the blackhead engines

 

[Mike Hughes]

Are you referring to the blue head era

Yes and no. The round bottom and square bottom EXR era. Some were silver, some blue, and a very small batch of black heads. Just before they change the crank size to 8mm on the 2K piccos. It is not the 2K black heads. It is too simple of a sleeve design. I believe it was before EXR.

I have the same P-45. To my knowledge, this was the first P-45 that Picco introduced. The head button sits on top of the cylinder. The second generation P-45 had fins on the exhaust stub. The head button protrude into the sleeve. From your pictures, it looks like sleeve 1, 2, 3 should fit your engine. You also have two head buttons (2 and 3) that fit on top of the sleeve.

Here is a shot of mine next to them notice my Piston is larger as is the sleeve

 

[jim kapanowski]

See the difference in the bore

Put a picture up so you can see the issue, the sleeve match up so I took the rod piston sleeve and installed it to see what works

 

[jim kapanowski]

As of this time #1 is not available

 

[David Bryant]

I believe it was before EXR.

I'm thinking it's for a P45 released between like 1988 - 1993

 

[Kez]

I can see the difference just from the picture. I am now wondering if the smaller p/l is for a .40. I believe Picco released a .40 aero version at the time.

I just looked it up. Picco .40 has a bore of 20mm. That's 0.787". I think your smaller p/l are indeed for a .40

My first 45 was a P 45 in 1984. The bore was .858”. Jeff Lutz
