Changing Oil (4-tec)

[sporsterjoel]

Just crossed my mind, was wondering wheni should change the oil, how many hrs is recommended between oil changes? id say on average i put on 10hrs EVERY weekend...

Thats alot of hours. I only put on about 5-6 hours in 2 days. Do yourself a favor and go to sears right NOW. And buy the $5.00 hour meter in the lawnmower section. Its very small and fits perfect in the engine compartment. No wire splicing needed. All you do is wrap a small pickup wire around a sparkplug wire and your set!! The wire senses the signal when the engine is turned on and it starts reading your hours from then on. Its the size of an automotive keyfob (keyless entry controll). Im not sure on how many hours to change the oil. Are you revving high RPM's all the time? If so then you gotta change it more often. In this case every 30 hours or check to see if the color is too dark.

Thats not a bad idea, and i wouldnt say i rev it high all the time id say i cruz at around 5600rpm's most of the time and most of though's hr's i put on are because i do alot of wakeboardin/skiin....

I own a 2006 Challenger SC 4-TEC. Your estimate sounds like a lot of hours!! How many time you filling up your tank!! You can estimate your hours based on fuel consumption. Seadoo spec. quotes approximately 9 gph (gals per hour), so with a 28 gal tank it is about 3 hrs crusing. However they do not provide the crusing speed/rpm but I assume it is much faster than skiing speeds of 25pmh.:cheers:

The recommended time on the oil change from seadoo is the first 10 hour break in and than every 100 hours. Here is the procedure to changing your oil too. You can order all the items needed from the "parts" link at the top also, except the Oil Extractor...go to West Marine.

Changing the oil on a 4-tec engine…all models

Here is the info on the oil change. If you still need info let me know. I own a 200 speedster 310 hp.
Here are the part numbers you need to change the oil and filter in ALL 4-tec engines.
(3) "O" rings
1)420320920-$7.25
2)420850500-$8.99
3)420950860-$2.20

Oil filter /I use a K&N off their website.
1)KN556-$12.95

Oil 10w40 Mineral Oil from seadoo#219700346-$6.50 a qt.
Be sure you use 10w40, marine 4 stroke Oil, with a API of SL, SJ or SN.
You need 3 L or 2.7 us quarts with filter for oil change.

Oil extractor from West Marine. Company Tempo, Part# 170200 Model# OB5 Retails about $50.00.
Change the oil when it is warm. Rev the engine to 4,000 rpm for 10 sec. and shut off at this rpm. This moves all the oil from the pto housing to the oil tank for maximum draining. Remove the oil filler cap and the dipstick. Insert the extractor tube in the dipstick 18.7 inches from the top of the dipstick pipe. Wrap tape around the tube to be sure it is in that deep. Next, extract the oil from the dipstick. (on pwc models only, the next step applies)When no more oil is extracted, pull the tube out of the dipstick hole and crank the engine(do not start) while the engine is in drown mode(fully depress the throttle lever, or on Jet Boats grab the throttle cable linkage at the throttle body and HOLD it open than crank the engine, get a friend to help)
Crank the engine for 10 seconds, Extract oil again, repeat crank extract 2-3 more times.
Keep track of how much oil you extract and add what you removed.

You will need a E-10 star socket or a 8mm(6pt) socket to remove the oil filter cap. There are 3 "O" rings in the filter cap area if they are damaged change them. Check level, and go have fun.
I hope this info helps.
