Cooling line questions 90 SJ project

[Wayneblaster]

Hey, newbie here picked up a 90 SJ project no telling how long since it ran last. Hull full of water mounts broke etc. Motor 650 has good compression 170 on both. It came with a protect BDP pipe . Hose off stinger where pipe attaches to rubber exhaust tube needs to hook to what? How's this work ? Water line from pump attaches bottom back exhaust manifold ,water goes thru engine comes out head then there's a t to pisser line runs to bottom of part one of pipe ?Then there's a outlet near rubber coupler that attaches the black curve to stainless pipe does that connect to outlet on stinger on stainless pipe?thanks in advance for any advice . Confused in cen tex

pump into bottom of exhaust manifold
out of head to T to bottom of headpipe and pisser 4 mm restricted
out headpipe to stinger with FCV inline

Thank for your reply tor p do . I suppose FCV is a flow control valve and the t to pisser is still in between head and inlet bottom of exhaust manifold black piece . My pisser is a hose off a toilet water supply line , looks to be 5/16 inside . Can I run it like this for awhile if I take it easy on full blast runs? No control valve and big pisser , restrict pisser?

That will dump too much water overboard and could overheat pipe.
Make a restrictor.
fcv is optional, gives snappier bottom end

Thanks again for the reply tor p do I'll scale down the pisser. Guy I got it from told hose broke and the only thing they had at the lake house was a old hose from a toilet took the outlet off couple sticking out of hull.I had installed a 701 the starter was bad so I decided to try the motor it came with, maybe I should of switched starters the starter was stuck on the 650 inside and out pulled it off shot spray White lithium grease in it seems to work fine?Ive more time than $$.
