Hello, I am a new boat owner(again) and now own my first inboard powered boat. I have some general questions I hope some experienced owners can answer. It is a 1982 Glastron 19.5 ft deck (SV191) with a 260 HP Merc. I would like some tips on what, if any, problems were common with these boats/engines/outdrives. I am unsure of the exact model outdrive I have, it just reads Mercruiser on it. Also, what kind of performance should be expected? I took it out for the first time today and was very impressed. I never tried to top it out, but it hit 40 without much effort and pulled a big tube like it wasnt even back there. Basically, what things should I check to make sure there are no probs, beyond the obvious? Also, do you check the gear oil in the outdrive by taking out the screw towards the top of the drive? It is labeled "L vent", not what I would expect on a lube level check screw. Sorry for so many questions, I will stop for now.

Thanks.

Re: New boat owner with questions

IS there a ser# on your out drive,that will tell you what it is. The top screw is were you take off to allow it to over flow when you fill it. Look toward the bottom for similar fitting thats were you connect to fill your drive.Every one will tell you to get the correct manual(s) for your boat,NOT SELOC to confusing to follow, Welcome to Iboats, Kick A.. site.>>>PAT

Also, assuming someone can tell me the make of the drive, could you tell me where to get an owners manual for it as well the engine?

Re: New boat owner with questions

Well, I posted to this thread once and it went away. So lets try this again.

The 6088716 is your serial number for the drive. It's a Merc "One" drive. You need Service manual #4 (Merc PN 90-86137)
Ebay would be the best place to find it.

Here is a site that will help you with some of your drive questions.

Re: New boat owner with questions

Thanks Don, will check it out. What are the general opinions of these drives? Any trouble spots to watch for?

Another general question i have is about oil pressure. Assuming the gauge is correct, it seems high to me. Gets around 80 psi at times. Also operating temps seem low to me. Around 140-160. Are these numbers typical of marine engines?

Re: New boat owner with questions

You should have asked those questions BEFORE you bought the boat, not after.
The drives are fine if you keep up with maintenance and the temps are normal.
Oil pressure may be that high when cold, but not warm.

Boat is in great shape, got it for a good price. I would have bought it either way. Just curious about any deficiencies of my setup.

The oil pressure typically is around 60, as low as 40. A couple times under hard acceleration I noticed it got near 80. Is there something I should check?

Re: New boat owner with questions

Operating temp sound good, it should be lower than your car runs.

Next, get a mechanical guage to check your oil pressure.

Re: New boat owner with questions

My setup is exactly the same as yours. My father in law bought the boat new. Mine has about 220 Hrs. on it and has never had any major problems. I've replaced the impeller and the trim limit and sender. This spring I had to replace the trim hoses from the pump and anti-reverse lock the the gimbal housing. They had a seeping leak in them at the end of last season. We were out all day today and I saw my temp gauge barely creep above 150 once. The water is still pretty cool here though. I'll see it get to 170 at times in the middle of summer. My oil gauge will sit at 40 psi on a cold start. If i'm idling at 5mph down the canal it will sit on 20. WFO down the lake 40 psi. Mines a 19 ft deckboat and it will do 52 with 4 on board. 19 pitch prop. I ordered all my manuals from Merc. Best investment you'll ever make if you plan on taking care of it. Have Fun!

Thanks. Mine is in an 82 Glastron 19.5 deck. It shows 149 hrs. All seems well so far. I dont really know what to look for, but have looked it over and not found anything wrong.

Does anybody know where I can get a custom fit cover for my Glastron SV191? I can find covers for it, but want one that is made for this boat.

Re: New boat owner with questions

Guys I had the boat out again today. Everything went great, but I have a question. What RPM should it reach at WOT? It didnt seem to want to get over the about 3800-3900. That was trimmed all the way down. If I trimmed it up, it didnt seem to help. Any ideas?

BTW, at 3800 RPM I was running 42 or so.

Re: New boat owner with questions

Do you have a TILT up/down button and a TRIM button?? mine does, First I have my TILT all the way down when I first engage forward throttle as I gain speed I raise the TILT up,boat is gliding now on top of the water (not digging bow) once every thing feel good and smooth(don't feel the waves any more) Thats when I hit the TRIM button and feels and performs even better, Thats when I know it's at its peek proformance. >>>PAT/I]

Re: New boat owner with questions

Mine has one button on the throttle(thats the one I call Trim) and the only other button related to this would be a button on the console that says trailer up or down. Is this the one you call tilt? I only use it to tilt the drive all the way up for trailering.
