    LH or RH Propeller Drive Unit

    Years ago when I started working on these drives that confused me too. But you have to think what the prop is doing in the water. On a RH rotation when in forward the engine is trying to turn to the right and the water is resisting pushing back to the left. So you can't turn it left because...

    Lower Shift Cable Housing Damaged

    Installing a new lower shift cable in my MC-1 and the new core wire wont go inside the cable. It goes in about 8 inches and stops solid. And I mean solid. No chance it will work. I've emailed Quicksilver to see if they will replace it. I can only find kits for sale and I only need a new...

    Seized Lower Shift Cable Nut

    Thanks nola mike. Interesting tool. Wish I had it yesterday. But I finally got it out. I used a punch to fracture the nut. I was then able to run the straight tap though the housing.

    Seized Lower Shift Cable Nut

    Need some ideas. When I started to remove the lower shift cable nut on my MC-1 outdrive the nut facets rounded over. So I drilled the center out and used some heat on the casting. No luck. The nut split. I'm stumped. Any ideas? Really hard to get into the cavity to work.

    Tilt / Trim problems :(

    I have a 1976 Sea Ray with original trim pump. Last week it labored to run and would finally go only go one way, up. I remove the upper motor cap and the brushes were totally worn/gone. Found a similar pair of brushes at our local ACE. With minor modification I was able to install them...

    Thanks for all these videos but my eyes just glaze over. I do not understand any of this. Frequencies, band widths etc. What the hell? For dummies please.

    What depth/fish finder do I want

    I have a 20 foot SRV SeaRay and want to add a depth finder. I boat mainly in the Illinois river and a depth finder would be valuable. I'm not a fisherman but it looks like a fish finder is the answer. I don't understand all the ads. What is the most practical for me? What is Chirp? What...
