Ok scratch head
Just where does one hook up a psi fitting on an old xflow??????????
Have looked all over found no 1/4 plugs and what hoses there are are quite larger and short,with no way to put in a T connection as not same size line.

Re: Ok scratch head
Don't know about the xflows.Seems like if you could fine a pressureized line you could tap in with a Tee and reduce one side down to the 1/4".
What about the pee line?

Re: Ok scratch head
There arnt any 1/4 taps,and two lines on it are like 3/4 and 3 in long,one would think they would make a 3/4 hose with a 1/4 off fitting.
Suggestions all over the net as to where to drill to place a tap in,many of them ill advised.
They dont even have the speedo 1/4 or id hook to it.
Am curious as to how others got around it or just running without psi gauge,something I dont desire to do.

Re: Ok scratch head
im t'ed to the pisser some respectable folks over at iboats and scream and fly recomend this and 15 pounds pressure for the older xflows bubble backs (not sure urs is a bubble back or not ) there isnt any fittings u can take out of block and put a guage like on a merc if u want one in the block ull have to drill and tap the block ..i was told the pissr would have the same psi as any water passage in the block cause threw out the motor it will be the same pressure cause theres more in flow than there can be out flow .. i confirmed this theroy ( i thought cause the pisser is restrictive and small it might show exessive psi that realy isnt there) by running the guage ted to the open pisser with no motor fitting to futher restrict the pressure i at the time had 26psi then i completly pluged the pisser after the t and got 26 psi at wot..

Re: Ok scratch head
Mine has two pea holes,rather large ones guessing 3/4 in each,did you tap them to accept a T fitting,got a pic?
All my other omc also had a fitting not just mercs,just apparently lacking in earlier years,in my own earlier years didnt know what a psi gauge was do didnt miss any fitting.

Re: Ok scratch head
year dunno guy said was 78-79 and in model numbers its got 77 s at teh end,its not a 77 as not hydro mecanical shifter
serial numbers have an 83 other numbers then an 84,guessing its one of the ,latter
two hoses one each side of motor going to below the bubbleback directly below are two half in pea holes
motor sounds great part due to those holes also some exhaust I think
my camera is defunct or id show you a pick,and thats where i thought id take it from yet hard to go from 1/2 or so to 1/4 and keep it all inside the cover
Im thinking now exterioer on those 1/2 holes for pea,maybe threaded plastic ,drill then put in a 1/4,all in an open t so even if it came out no problem,just thought it would read low myself
