Oil Change

[Vortexman]

Hi everyone,

Hope that everyone had a good summer and fun on the boats!! I know that the wife and I did. I have been really busy so have not been able to come onto the boards very often.

Anyway, just wanted to pick your brains again about oil. I am going to change the oil it the 496HO. I am hoping to do a couple of winter runs to Mohave but we will have to see how it goes. The Manual recomends 25 40. I am sure that I will be fine if I use that but does anyone else have any recomendations?

Thanks in advance

I use 10w40 in mine.....

Long time no see on the boards there dude....Good to know you're still alive and boating, see ya out there http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/wink.gif

OIL?? DID SOMEONE SAY OIL??? most of my customers, along with myself, run a 20w50. regardless of what weight you decide on, i'd go with a quality synthetic. the biggest concern with boat motors is the fact that they will generally run a little hotter and stay under a heavier load (higher rpm)than a car/truck will. you can check out my website www.lubedealer.com/extremelubricants or send me a pm/email.

AMSOIL 20 50

Great stuff. http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/beerchug.gif http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/thumb.gif http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/jump.gif

Not to throw a loop into the discussion...but....the latest Powerboat Magazine on the stands (last issue as I haven't seen another in about a month) has a long technical question answered by Bob Teague on oils. You might want to read up on it. I personally run Kendall Racing 40wt as recommended by Bob Teague in the motor.

Agreed with other posts. Teague and others that tend to have their engines under extreme load (i.e., lots of WOT and racing around) recommend a straight 40weight. My engine builder does as well if in a racing application. However, Volvo and the guys that built my engine recommend a synthetic 15/50 or 20/50 if going more recreational. I use Mobile 1 15/50 synthetic and I hear the Amsoil product is great as well. Also, if in a big block over 500hp application, change the oil every 10-20 hours, and cut the filter occasionally to see what kind of debris buildup is occurring.
The latest issue of HOt Boat had a good article with pics on this last recommendation.

I use straight 40 Delo by Chevron. Everything I have read recommends straight 40 unless you're running synthetic, then you can use 25/50.

Thanks for all the info guys.

What all do you guys do to winterize the boats? I have an idea but just wondering what all of you do.

thanks.

I write an ongoing list because I am pretty brain dead about these things and tend to forget something. It also helps when I come in to a shop and ramble on about what I want done. Here goes:


Change out impeller.
Spark plugs and cylinders … mist and replace spark plugs (every 100 hrs) as necessary.
Drive oil drain and replace / Align drive (merc every season, Volvo every 3 seasons).
Fuel filters and water separators replace.
Flame arrestor -- remove, soak in cleaner, and clean.
Heat exchanger … check pencil zincs and winterize.
Flush sea strainer.
Stabil the gas, top off, and run.
Change oil 15W50 and filter.

Check out trailer and repack bearing buddies, inflate tires, and WD40 all working parts so it soaks all winter. Move trailer a bit every month so that tires do not sit in one place.

Two coats wax on all gel -- hull and interior.

Clean and repair all vinyl ... use a West Marine product (cannot remember) to coat and protect vinyl and keep all pliable.

Spray another West Marine product (cannot remember) on all bimini top cloth to UV protect and lengthen lifespan.

Check battery cables, spray/lube connections, and hook up battery charger for winter. Go out onece or twice a month and check on all.

... and this is an important one ... go over all screws, nuts, bolts, fasteners, hoses and etc. on entire boat (engine compartment, fuel lines, rub rail, hatches, etc. and etc.) to tighten and replace as necessary. Saves breakdown in the spring and with all the WOT pounding around many things you don't think about come loose and break if you do not attend to.

Rub on the hull and tell the boat I love her, play the stereo full blast in the storage unit, drink beers and make engine sounds with whomever is with me as I pretend to check things over regularly http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/smile.gif.

i think that's the one boating mag i don't get http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/biggrin.gif can you give me a "reader's digest" version of what they said?

[Essex502]

Basically, a reader wrote in refuting Bob Teague's recommendations to NOT put synthetic in the motor. The reader had actually made a trip to the Amsoil headquarters and talked to their engineers. Bob cited this and that - reasons not to use synthetic oils.

I think - without rereading it - most of his objections centered around abnormal wear that he has seen on the roller rocker arm tips. He theory is that the lubricity of the syn oils don't allow the rollers to roll and they slide causing flat spots. I'll try to scan the article and post it. In a few months it will be on Powerboat's website as they are always a few months behind to not steal sales from the mag.

It was interesting talk on oils not that I subscribe to all of his theories. Bob is an Amsoil dealer and sells it out of his place in Valencia, CA. He does recommend syn lubricants in the outdrives.

I've heard that also about putting synthetic in a roller motor, not sure where though, maybe Hot Boat.

i have also heard this before. it doesn't seem to make much sense to me. if you are having abnormal wear on a motor having to do with roller rockers not working properly, it sounds more like a clearance issue. i've never built a motor but i wouldn't see how you could blame something like that on the oil used. i'm on the phone with amsoil's tech line on a very regular basis and they have never mentioned anything even remotely close to something like that (not that they would be a little biased or anything http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/biggrin.gif ) i may have to see if i can find the article this weekend, it should make for some intersting reading. http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/smile.gif

I re-read the article last night and here's the gist of it:

Bob Teague says he's seen abnormal wear on the roller tip of hydraulic roller lifters. Also, the needle beings of those lifters shown abnormal wear. His definition of "abnormal wear is flat spots. Apparently, the spring pressures for the more radical cam profiles don't allow the roller tips to roll but slide with the better lubricity of a synthetic. This applies only to motors using hydraulic roller lifters. Solid roller lifters and normal hydraulic lifters (no rollers on tips) are OK in Bob's mind for use with synthetics. He actually recommended that if a synthetic is used in the 502 MAG's to use Amsoil 20W-50. Bob is an Amsoil dealer. He also recommended the sythetics in outdrives EXCEPT number six's. I guess it is pretty specific which motors have or don't have the hydraulic roller lifters.

Hope that helps...short of retyping the entire article that's the best I can do!

thanx!! much appreciated. one of these days, i'm gonna have to get with some of you gear heads and have you's explain the differences in all of this stuff to me. i'm really wishing i would have taken some of them vo-tec classes now http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/cool.gif http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/smile.gif
