Hello. I have purchased a 1981 Lancer 25 . It is a Mark IV or Mark V. It has no mast support pole in cabin and has the six ports. I have been given conflicting stories. I know saildata says Mark V is 1982 on. Thanks for any insight.

I believe ALL the variations up to IV have the compression post.

The only model without is the V.
