As originally equipped, what dia. was water inlet hose from thru-hull to water strainer?
I have a Vetus basket type strainer with 1" in and out. I think it is original. I ask because of all the Home Depot pipe/reducers/clamps/laundry hoses/pvc/ball valves, etc. that was done before my time.... Thanks |

An inch ID.
On a PCM 351 everything from the thru hull fitting up to the RWP is an inch. The outlet from the RWP is an inch And I think Zach mentioned in your other thread the hoses from the thermostat housing to the manifolds are .............an inch. |

I thank you.
Yes, Zach helped me with t-stat hoses. I'll buy plenty of 1". I'll get some photos up soon of the 'lightweight' 351 and the modified cooling system... Actually just brought the boat around from the barn today. Sun is out! |

You talked about a crank driven RWP at some point in the recent past.
If you got one, does it have 1 inch connections ? Only reason I ask is because the typical crank driven pump on an Indmar 351W has 1 1/4 inch fittings. There must be a crank driven pump out there with 1 inch fittings though. |

you're right..
I had a Johnson crank rwp knocking around, am using it on my build. It is 1 1/4" both in and out. It will feed into a "gutted" circ pump (now just a manifold) and exit into a modified t-stat housing, then to exhaust. Also a couple hoses to bleed off excess rwp pressure. Actually very straightforward. just hope it works as planned...

12 feet is usually enough to take care of a PCM Ford in any CC boat, Maybe a little extra but it's better to be too long than too short.....

Well that took a hard 90
 Seriously though, is it about the same for the 90's era SN? I figure 75-80% of everything else is going to be new and considering there was only a handful of hose, pipe or wire in the entire mess that hadn't been spliced at least once .... |
