Hey all. Wow, I take a 2 year leave, and this site goes ALL OFFICIAL. :D

anyways, Ive got the In-laws into boating now, and they got their own boat with its own problems.
Its been sitting in a garage, out of the weather, for about a decade. and this thing is beautiful!! but, I think the sitting has caused some of the problems.

Its an '85 Mercruiser, chev 305 4-bbl. Theres only 2 problems with it, and I hope theyre related.
One is the Dying problem that happens every time it shifts into (either) gear. With ya'lls help, I went out and believe it is (one of) the shift cables. The Y-actuater is moving as the cable moves into gear, activating the safety switch, and killing the motor. So, That IS the cable, right??

The second is a little more tricky: moving the shifter into reverse, the motor throttles up, but it never goes into gear. Not even the clicking noises I could hope for. I would believe its out of adjustment, but they say it was working when it was parked, so Im not totally sure.
If it is also the cable(s) causing the problem: How hard is it to change??
any tricks or snags that would get me lynched by the in-law mob?

Im pretty competent on autos, but boats is hit-n-miss..
I have the guide in the adults section, and the paper book on mercruisers, but I find much difference between theory and practice, so I ask ya'll who have done this before.

Thanks much in advance,
Jon.

Yes, soundls like a bad lower shift cable causing it to die.

The second is a little more tricky: moving the shifter into reverse, the motor throttles up, but it never goes into gear.

After you get the new cable adjusted, I would bet this one cures itself also.

Thanks Don, Thats really what I wanted to hear. Also, How hard is it to DIY? (well, DIM I guess.) :)

Is there any adjustments that would really mess up the outdrive? I'd be doing it on muffs, so theres no load. and I can understand the basics of whats goin on.. but I really dont want to mess up someone else's boat.

Take a look in the Mercruiser maintenance manual.
