Hi,

I am overseas, so access to skilled service is limited. Looking for advice based on forums experience. I have a 1999 350 Mariner with twin Crusader 5.7 MPI V drive. Port engine seized. I had someone take for me to get registration done and assuming after that last run, something leaked and due to my travel schedule wasn't discovered until return and found would not turn over. FWC reservoir dry. I spoke with the shop manager at the marina I usually do my haul outs at about rebuild and repair. His comeback was startling, he didn't have any skilled petrol engine mechanics and he couldn't recommend anyone in the local market he would trust. So I am faced with either a rebuild, getting a base engine and bolting on 24 year old components, or buying 6L crusader complete drop in (I am told 5.7MPI no longer available, so latter means 2 engines). The 6L is certainly an upgrade with added FWC also to the manifolds, but do i want to spend 16K time 2 on 24 year old boat. Ordering a base engine opens up a pandora box of finding other issues with bolt on parts and availability in an area where I have been warned of lack of skill.

Note, the boat was originally on a lake, so the FWC was added after by Florida dealer, so no factory FWC. Otherwise condition of the boat is excellent.

Has anyone re-powered this era of Mariner with the newer 6L? any fit issues? I assume that crusader to crusader will have some common connections, wiring harness etc.

appreciate any feedback Thanks
