    Nissan 9.9 2 stroke stuck lower unit

    Trying to remove lower unit. It uses 4 studs and nuts. I've been soaking the stud area and all around the parting line of the unit to exhaust housing for a week. Tried heating the area around the studs. It won't even drop enough to get a screwdriver between them. I tried hitting the lower unit...

    Yamaha 130 v4 idle mix screws

    My 2001 130 v4 loads up when running at a fast idle say 1100 to 1500 rpm range. It doesn't stall but you can tell it's not as smooth as it should be. I set the screws to factory spec bur may need some finite adjustments? On my last 115 v4 I remember not noticing a perceived change when adjusting...

    Yamaha 130 hp oil pump rod adjustment

    My 2001 130 hp v4. When I adjust the oil pump lever clip at the oil pump arm I'm having a little trouble. If I adjust it so the lever hits the pin on the pump (low speed throttle closed position) it short changes the pin at full throttle. It just about makes it to the full throttle pin on the...

    Yamaha 130 2 stroke height

    Seems strange that the anode would cause a bigger v spray at the higher engine mounting position? Do you think maybe the water coming off the bottom of the hull is deflecting off that ribbed section of the motor?

    Yamaha 130 2 stroke height

    I tried it without it and it was worse. Lot more bow rise and more sensitive to porpoising.

    No feedback helm question

    Just wondering if it's OK for there to be about 2 inches of back and forth when you push on the outboard as if trying to steer left or right? I know the design of the helm won't allow you to manually steer the motor when pushing on the motor one way or other but I have little play back and...

    Yamaha 130 2 stroke height

    So I'm thinking the v spray ( v like spray coming from each side of motor) is coming from that ribbed section above the cav plate seen in the front of the outboard. With the motor mounted in hole number 3 during testing the v spray was worse then when mounted in hole number 2. For this...

    Yamaha 130 2 stroke height

    Tried it 1 hole up (2nd hole down from top). Big improvements but still didn't see cav plate in video. Wound up moving it up another hole ( 3rd hole down from top). Cav plate visible in video. No prop blowout on turns. Only thing is I noticed a v spray of water out to each side of the motor...

Not much for weight up in the front except the anchor. I guess I could throw some weight up in the anchor locker. Maybe something kind...

    How to video cavitation plate on the water

    I don't have anyone to go with me plus I'm trying to keep weight the same in the boat for testing. I believe my motor might be mounted too low. Anyone have suggestions on how to rig a camera to see the cav plate when underway?

    Yamaha 130 2 stroke height

    If the water is nice and flat I can trim up to about 1/2 on the guage but it's rarely flat and calm.

    Yamaha 130 2 stroke height

    1997 wellcraft 190ccf center console. 2001 yamaha 130 v4 20 " . Noticed a good deal of porpoising and I can only trim up not even 1/4 ot the trim guage. Also seems like a lot of spray ( whole back of the boat gets wet after running). I can't go back and see where the cav plate is when planing...
