you are describing exactly tha way some act straight outta tha box from merc with tha way it cools.. we called it "consumer R&D"....
yep... restricting tha discharge from tha poppet will slightlt increase tha pressure with most motors but not all.. it still depends on tha drain holes in tha...
"Now on the one-piece plate the 2.4 dump hole were pretty close to the right size but I still modify them. The 2.5 plate dump holes were all over the place. I have seen some that were so big the motor could not get more than 5-lbs. water pressure at 9000 RPM. I weld up or tap and brass plug all...
jus for info.. do you are anyone helping you have any experience with tha V6 merc??? as for your concern with pressure go here, follow his specs, and your concerns will go away... might as well pull tha powerhead and check this.... yours (adapter, coolin' system) is tha same as his BIG motors...
ya need a spark tester or use your timin' lite ta test for fire on each clyinder off idle..................... or if ya like me i sometimes pull one plug completely out and start tha thing... do all six undividedly... you can wait till dark if ya have trouble seen' any spark from tha plugs.. but...
look here for a build date stamp.. may not be very readable but its there on tha block somewhere... should be area "behind tha advance timin' arm", kinda behind tha bend in tha arm....
chris, his motor has tha older WH's that have been changed which do not have anyway ta change idle except jetting.. his motor came with WMH's...

thats a painted light weight.. you must have tha high performance XR2.. mount for tha hi perf. lite weght cowl also... thats a completely different story.......... not many of those left, especially here in tha states............
got my attention now.. what boat is it on?.. pictures?
agree with fast... something jus don't look right??? buy it used?.. acoupla more pics would verify?.. jus powerhead.. both sides and rear..
merc didn't build a '93 XR2.....
its common for some to run their main tank at 100 ta 1 with tha older motors jus for a little peace of mind and not totally confident with tha oiler workin'
reed plate and front half gotta match.. merc only built one 2.4 seven petal "production" model front and that was in '80 and '81.. they only built one 7 petal "production" 2.5 seven petal in '91.. other than those all other production motors were five's............
were tha ones ya bought straight thru or one-way bibs?.. what reed plate.. they only make two and they need ta match tha front half?.. tha one (pressed in bib) in tha pic is a five petal.. tha only other one is a seven petal.. jus curious as to what ya buildin'?.....
is tha one with tha...
