I am looking to buy these parts for both motors in my Formula. 3" risers and either style of thermostat housing.

If anyone can help me out, please let me know. Pictures of parts below.

Thank you, brian




or these

ebay

Been watching ebay, not much on there. someone there is selling the GLM's 3" for $104 del and the 4" for $127. Haven't been watching the 4" much untill you mentioned those details by PM.

The problem is, Mercruiser has a high list price on these so everyone seems to think there used ones are worth $75 + del. I was just trying not to spend $420 on exhaust parts for a 26 year old boat, but guess I was dreaming.

The lower priced ones I have seen I have requested more pictures off and the rust scale in them indicates they are going to soon have the same problem mine have, the outlet is rusted shut between the casting and inner sleave. If spending $420, I should just spend the $630 for aluminum GLM's and be done with the rust.

If this doesn't pan out, srill looking at just making a set.

What do you need manifolds also.JOHN SR

My exhaust manifolds look fine, stock cast iron mercruiser units. Those cleaned up nicely.
