I have an 87 black max 135 that seems to be running hot on high rpm but cools right down at lower rpm. New pump kit, poppet and stats. And help would be appreciated. https://youtu.be/0qVqIaayfw4
Just bought this boat and motor, didn't take a pic of the Vin sorry. Was told it has an intermittent alarm that sounds and should ignore it. I have been an i/o guy for a while and my first outboard built after the 60's. If you have time please check out the video and any input would be...
Hey everyone, back again. Been chasing an overheat on plane issue from last year. Replaced the water pump base last year but when I put the hose in the pump pipe I see water spraying from the base. Take a look and let me know what you think. As always thank you for all your knowledge...
Working on the boat dropped the lower and the copper tube came out still in pump. Went to push it back into the pocket and loose as a goose. Never had this happen before. Other times the tube seemed snug in the pocket. Normal? Should there be an option ring or something to seal and...

Just changed engine and kind of paranoid so sorry for the noobish question. The weight I should put in the boat 25-40 or 15-40 not the 10-30 on the automotive cap. Thanks.

Finally got new engine in but one of the pin connectors pulled out on removal. Does anyone know which wire the gray one on the boat side of harness connect to thanks guys
Well boats be running rough this year and last I guess. Number 4 wasn't kicking had spark so ran a compressiontest. Hope the tool was little off. Readings in psi from 1_4. 70, 70, 90, 0. Gunna pull the head and see what's goin on. Hope I head gasket will make her happy enough. Any thoughts...
1984 bayliner 25 ft cuddy. Buddy just got it and won't trim down. The motor has only one solenoid. Control is the old 3 button type. Hit down the trim motor chugs along but doesn't whine like i usually hear. 12.8 volts to all the connections. Oil is full. There are only 2 lines out the bottom of...
