    90hp v4 crossflow to 140hp build

    That green area is what you'd need to drill or mill out for the bubbleback. But has anyone ignored that? id think it wouldn't hurt much as it divides the bubble back exhaust better for more exit velocity vs. being open but I dunno. BTW this is an XP/GT 100 that has the 140 ports.

    1994 Evinrude 140 water pump question

    these use a LOW pressure pump. combined with the anti-siphon water pan sucker 9000, they usually just dribble out at idle. the ONLY thing that matters is cyl head temp at idle in the water. the flat spot TOP of each head must be 125-155f ! people obsess over the indicator flow but that means...

    67 Year Old Head Bolts

    no i meant in the powerhead itself. the exhaust cover and plate. if the tuner/tube in the midsection looks like that, imagine whats on the exhaust side of powerhead! and for that you do need to remove the plate as you will get crud in the cylinders

    67 Year Old Head Bolts

    the real fun on these starts when you need to take off the exhaust to clean the carbon out. 9 out of 10 of these have horrible carbon buildup from hours of slow trolling on inferior oil. those tiny #10 flathead aluminum screws will just snap if you dont take a week to get em out

    1977 70 hp johnson thermostat housing gasket

    now all you need is the t stat, x2 grommets and the cork t stat round gasket. this is on ebay. tons of springs available. just a thin coat of permatex aviation around the old t stat housing gasket and its usually just fine.

    Yamaha F225 ECU Upgrade

    i think you are being a bit paranoid about engine temp. Im an outboard rebuilder, and the only times youd see an overheat is from sucking up weeds at idle (would need to be a huge patch of seaweed to wrap around the gearcase to drop pressure at intakes) or a clogged t stat but these issues are...

    Opinions needed - Risk of Changing Thermostat

    i have literally dozens of fully tested used 200f temp senders. they came in basically every motor from 1978 or so on up through late 80's when the charged to the tan/blue stripe which was around 240f. i usually replace the 240f ones with the solid tan 200f. the quickstart ones are impossible to...

    87 50HP VRO Evinrude - Could this be my problem?

    that rectifier will absolutely get damaged with that lipo battery IMO. lead acid only. how does the tach work smoothly? those delicate diodes in the rectifier dont like that. you can get the maintenance free upgraded CDI rectifier (regulated) for about $120 then you can technically use cheap...

    87 50HP VRO Evinrude - Could this be my problem?

    those suggestions for setting the throttle cable are critical, and DEAD WRONG here if you have the common side mount control box. its set in FORWARD detent and the lash is pulled out then set the thumbwheel adjusted to trunnion pocket making sure the slow speed screw is FIRMLY against the block...

    1978 Johnson 140hp running rough. Need advice

    i said the piston crowns soak up heat hence the premium fuel recommendation. I know it will run fine on lawnmower gas...

    1978 Johnson 140hp running rough. Need advice

    agreed. problem is these crossflows run hot/lean in the midrange. those thick piston crows soak up a LOT of heat!

    1995 Johnson 150 shuts down after 5 minutes of full throttle

    the vapor separator pump... when running, pull its recirc hose out of its hole in the air silencer up top (it is in the hole, right?) you should easily feel it pulsing air . if ts very weak or nothing, simply remove the hoses to the pump, unscrew it from the separator cover, mark it with a paint...

    1978 Johnson 140hp running rough. Need advice

    for most engines thats very true, but not with these specific crossflow V motors! the heavy piston crowns soak up a lot of heat. add the other reasons I listed above and premium fuel is absolutely the logical/better choice. And no, it doesnt reduce power. if anything it increases it.

    1978 Johnson 140hp running rough. Need advice

    I would be planning on a rebuild as Racer said... 100-110psi is too low. those 78' 140's had very tight heads unless someone replaced them for crappy fuel. im sure it will run for quite a while so if thats all your after no worries, but it would be a different motor once properly bored and...

    1988 Johnson 70hp - VRO or not to VRO?

    the VRO/OMS pumps are extremely easy to test. you dont even need to remove it from the motor! Just need to remove the fuel out hose, and pulse hose. its a simple series of pressure/vacuum tests as clearly charted out in the service manual. that way there is no guessing "hmm maybe ill replace it...

    Attempting a motor rebuild

    sounds like you found a shop with a big fancy CNC machine thats set up for boring auto engine blocks. the absurd price is because it will take the guy a while to re-calibrate and set up the machine for your little tohatsu. flagship marine in punta gorda, FL is $35/hole finished.

    Attempting a motor rebuild

    the ring side-clearance tolerance in the piston is a whopping .004''. can you measure this with a feeler and get back to us? personally im not puttng a motor toghether with even .003'' but thats just me. the side effects include fun things like the motor feeling like its tied to a stump out of...
