Many people buy a costly telescope and then discover that they’re not actually interested in astronomy. And you will always appreciate having the binoculars, as well.It’s a truism that experience has no substitute, and there certainly is nothing better than using different telescopes before you buy one. This will help you to get the feel of all the types of telescopes and you will know which one is easier for YOU to use. A large aperture refractor may give you an excellent image but you may not be able to keep a steady hand while using it resulting in a blurry image.

Inline 4 and V6

Exhaust manifolds collect engine exhaust from the cylinders and send it to the exhaust pipe. The Mercruiser 2.5 L and 3.0 L Exhaust Manifold 120hp 140hp are made by GLM Products and fit most early 3.0L 181 CIC and 2.5L 153 CID that were used from 1968-1982. The 2.5 and 3.0L 120-140 hp Mercruiser Exhaust Manifold fits most late model 2.5 L 153 CID 120hp and 3.0L 181 CID 140hp used from 1982-1995. For 1990 and newer models, the Mercruiser exhaust manifolds 3.0 L LX fits the 3.0L 181 CID LX for 1990 and newer.

For Mercruiser V-6s, the Manifold Conversion Kit works with GM 262 CID blocks from 1996-2000 with raw water cooling, while the Mercruiser 4.3L V6 Exhaust Manifold fits all 4.3L Mercruiser center-rise manifolds. The version for the 4.3L V6 cast iron is for pre-1986 Mercruiser GM 4.3L V6s.
