Hi everyone, new to the forum, i have a -92 Baja 24 OL with a 502 mk4 closed cooling, it's time to service the raw water pump BUT i cant physically reach the damn pump, even being a scrawny dude i dont fit in the engine bay and be able to wrench, do i need to remove the whole back seat (got the top half slid off) so i can access it from the front?, or can i reach it if i remove the heat exchanger, right now it's about an inch gap between cooler and back seat, i expect it's "easier" to remove pump whole and service it on a bench right?.
I'm quite used to wrench on my own stuff but i have never worked on a big block in board, boy is everything cramped to reach.
Glad for any input/help!

Pull the entire assembly. It's much easier that way. When you put it all back together, use a hose lubricant on the fittings to make getting it out of the boat easier next time.
And I agree with farming the job out if it's next to impossible to get to.

I'm barely able to climb into the engine room and lay next to the engine to pull my pump off. I made a list of the tools needed so I don't have to climb in and out which really sucks. If you absolutely can't fit in there then I guess you'll have to hang upside down and hope you don't slide in and get stuck! Good luck. I do mine every two years now because they always still look good. If back seat removal gives you access then do that for sure. My boat has a bulkhead/firewall in front of the engine.
