    Estate sale lot of 18 - 25hp motors - Compression gauge variables.

    On the high compression one ..... I have seen 2/ motors with a small drilling , about 3mm, that goes from an area above the ex port on the cylinder wall to the roof of the port to act as a decompression port , others have a notch in the top of the port window, either way if it gets plugged with...

    Suzuki Kill Switch Issue

    The fact that this is the 2nd kill switch , and that the starter dont work in the "off" position and does in the "run" position strongly suggests to me that the switch aint the problem . It appears to be doing what it should . Check the fuses and then give the thing a real good eyeballing ...

    1981 Mercury 7.5 2 stroke

    FFS ! THERE IS NO DIFFERENCE, they just measure it at the engine speeds that provides the figures they are looking for. Anybody with half a brain and who doesnt feel the need to keep stirring the pot could (would ) see that, even the friggin Honda dealer said they are the same powerhead . You...

    1981 Mercury 7.5 2 stroke

    1981 Mercury 7.5 2 stroke

    yes , all the same , 808cc Nah ,the torque and power are the same . With the 45hp they may well measure peak hp and torque ( I doubt it as there is a 50hp the same size ) but with the 35 they measure it at the revs it produces 35 hp and then say " oh , this one is rated at 35 hp at 5000rpm...

    Timing is retarded ;-)

    Do these motors have knock sensors ? Is the fuel high enough octane and fresh-ish . My car needs 95 oct and if I feed it 91 it cuts back on something that noticeably limits hp.....I suspect the ignition advance with fuelling to suit Not that familiar with newer outboards but I am with...

    1981 Mercury 7.5 2 stroke

    The hole in the end of the crankshaft is usually there to enable the crankshaft to be pressed apart . A drift is placed in the hole and rested against the end of the middle main journal , wjth the crank properly supported the crank can be separated in to two halves to replace bearings and...

    1981 Mercury 7.5 2 stroke

    Outboard HP ratings can be weird I have a 35 hp honda that has 35 hp between 4600 and 5600rpm The 45hp has 45hp between 5 and 6000rpm and there aint a foot/lb difference in max torque between them just the 45 hp is max at 1000rpm higher. They are the same motor ( I have checked heaps...

    Lexus Oil Leaks and Mechanic (Woes)

    Mind you some cars dont help . I have a Toyota Blade ( Arius ) with a 2gr V6 and I had to remove the whole intake manifold assy to get at the 3 rear spark plugs .... pretty much a days work , where as my 1980 Ford Capri I can change the clutch in less time ..... and I can see the spark plugs

    Tohatsu M18d charging output

    I cant find any info on the charging system output . Im just figurin on battery drain verses charging input from the motor . I plan on having a house battery for my inflatable Flounder slayer.

    Listing to port side

    OK so its not unusual in your area. If its for putting the sneak on trout in small rocky streams was it actually designed to plane ? Im thinkin an electric motor would be better for sneaking up on Trout .... unless the "shallow rocky river " is also the local white water rafting hot spot...

    Listing to port side

    I cannot for the life of me see why that WOULDNT list to port . Looks to me like the add ons are an attempt to fix the issue . Dunno if its just the pic but that motor looks huge and I suspect that its way heavy . The way you describe the listing getting worse as speed increases suggest a...
