Alien cowl question

[racervboat]

So I got this cowl and it's aftermarket fiberglass bobs maybe ? It has a homemade alum plate for a 2.5. Is a alien 2.5 cowl the same size as a 3 liter cowl just the plate different? I ask cause I got two skirts with it one is glass like the cowl and is 18 inches wide and a factory plastic merc one is 16 1/2 inches wide ?

3l alien is taller, i have both sitting in my shop, the plates will be totally different,the 3l skirt is wider than a 2.5 as well

You should be using "blind" rubber nuts that squish down and surround the hole. This is what gives it some shock absortion as well as grip to the pan,and waterproofs the sealing area without a gasket in there. Size used by factory are simple 1/4" x 20 thread

Can you tell me how tall the 3L cowl is not sure about the one I have as the 2.5 plate was home made and put on this cowl?

Not sure why my pics get posted sideways on here, lol

The factory plastic one 16 1/2 inch wide fits my cowl perfect. The glass one is to wide,funny cause the cowl is glass so is the glass skirt but its to wide??

Well there have been some horrible ill fitting aftermarket partsaround for years.

So is this going on a 2.5 or 3l ? You have 2 totally different pan plates

I know the 2 plates are different it has a home made alum 2.5 plate now I bought a 260 cowl and he had this alien for cheap so I bought it just to have later for maybe another project.Could not pass it up cowl pan and two skirts in great shape and local no shipping for 200.00 bucks .
