    why does merc use two breather hoses and VP an intake

    curious as to the two designs and which performs better? im referring to the earlier vp/omc style with one hose to carb brake vac port vs two breathers going to arrestor on merc system..

    is there a 44" version of the gray pump hose (old style)?

    hi - this is an older i6, but no lockout - has a newer style pump with adapters to convert from the early style at the pump, however all the diagrams i found go via the rev lockout- could not find a matching gray hose in the same length as the black. I did find a set of lines at the shop that...

    is there a 44" version of the gray pump hose (old style)?

    All i seem to find is the 29" versions to the lockout valve, but i would like both hoses the same length - inline 6 with the trim pump mounted on the stbd side of the block.. For the black I have 32-59841 but not 100% sure what part number for the gray hose. fwiw this is the smaller (old) style...

    2000 vp 5.0 - can i use the closed tstat housing for raw conversion?

    Converting to raw as engine is old and not worth dumping $ into - suspecting HE blockage. Planning to put in large 2" hose from raw pump OUT to tstat IN and bypass the HE entirely. just not sure if the closed tstat housing differs from raw tstat housing - seemed to recall a bypass variance but...

    Mercruiser trim confusion - pur/wh trailer switch wire same as limit pur/wh bullet - why?

    Just found this on another thread which confirms my suspicions someone messed up the wiring - "OK well something is screwed up:confused:. The purple white wire in the back should come from the control handle trim up switch,"...

    Mercruiser trim confusion - pur/wh trailer switch wire same as limit pur/wh bullet - why?

    Have a 2000 maxum with twin controls. I know HOW trim wires work, but I cannot explain why the pur/wh limit switch bullet wire at the transom is connected to the TRAILER switch up front? Makes no sense. Surely the trailer switch pur/wh should be a power source and NOT the same as the pur/wh at...

    Wits end again - 75 V4 115. Will an oscilloscope help??

    I would imagine the seal would be double lip correct? When i removed the seal it only had one inward facing lip meaning the crankcase could potentially suck air. I have run new extra grounds - no change Also removed sanded greased all surfaces and connectors - no change. ITS NOT THE GROUNDS...

    Wits end again - 75 V4 115. Will an oscilloscope help??

    motor is def running on all 4- ive been analyzing the ignition graphs on each to look for oddities.. replaced all 4 carbs with oem ones yesterday - same issue. When i tried the open gap tester one of the fairly new sierra coils arc'd right thru the coil body to ground, and this was on a 1/2 gap-...

    Wits end again - 75 V4 115. Will an oscilloscope help??

    plugs good yes - i have an ignition analyzer with a graph and they all are kinda stable... but when it drops its not all the way down, like the whole system takes a hit, and its very all over the place.. shocks at the pack, dunno... been fiddling for hours, im trying to learn more than...

    So - working on this motor for a customer.. So far all the DVA and ohms readings check out. Ive eliminated a faulty tach/rect/kill circuit.. I started getting small shocks near the pack- im wondering if the insulation has broken down causing cross arcing and grounding out the 300v wires from...

    gen1 upper gears for ratio same as gen2?

    Will the upper driven gears from a gen1 fit gen2? I was sure the g2 has a different lower gear for the different seals - G1 uses large and small seal, G2 uses 2 small seals - I have a gen 1 upper mated to a 1980 model lower, and need to put in 1.84 gears for a 3.8L merc 17/19 tooth-. No SN on...

    bravo magnum - convert to accept trim senders?

    well poking around seems there are knurled press inserts- unfortunately just not for the 5/8 in marine stainless.. that would have been a real easy conversion! Hole is a few fractions less than 7/8..
