I have owned an 82 Marlin (18') now for several years, bought it when i was still in highschool...Had a mild built 454, 380hp on the dyno charts. I am getting gps'd 65mph out of it. All of the sudden, after years of using it, I have an urge to make it faster (Must be my brain maturing, right?). I'm getting around 5000 rpm's with I believe and ab impeller...not verified, going off previous owner. Motor only has 75 hours on it, bonus. I was going to run a droop, but saw I have the 12jc bowl, so thats out of the question. There is a loader grate, but it is partially blocked up the middle, about half way up the block ends. Would I be better off running a full block or a no block? Also, can anyone provide me with any info on these hulls...Through word of mouth I have heard that the guys building Marlin hulls split into another company or something along those lines...just curious if its a good hull or not. I'm going to blueprint the hull this winter and detail the jet as well.
ooooh yeah and it also has kodiak marine cast manifolds that collect into a single over transom pipe that were dry, but i tapped a water line into the ends to make it legal for PA waters. Should i ditch these and run headers? Have heard mixed reviews from people about how these chambered manifolds "feed" as they run into collectors, but I'm not really sure I understand that.
Any info or insight you guys could provide for me would be stellar!
Thats the only picture I have that shows anything remotely important...That was the day I got it!
