Just got new to me 2020 Supra SE450.
First surf boat for me.
How often do you change oil and what oil do you use?
Is there a drain hose?
Thx,
Don

The 450/460 calls for 15W50 and recommended interval from Indmar is 75 hours and yes there in a drain hose. If you idle a lot on a small lake and don’t run it hard enough. You can get fuel dilution of the oil and 25 hours is recommended.
Here is your Indmar Manual if you didn’t get one from previous owner.

I change every 50 hours with Mobil 1 15w50 and a good filter not Fram orange.
Drain hose is on the bottom of the oil pan. Has a hose that is probably clipped to the motor with something that looks like a shower curtain hook.
My SL hose can fit through the drain plug in the transom. I hook up a pump and suck it out.

Air hose fitting attached to oil line that routes to a pump.

Filter for my SL. The socket is the same size as my Ford Truck Diesel filter socket.

I have a 21 SL 450 and changed the oil at 20 hours, then 70 hours. 20 for the break-in period. I split the difference on 75 and 25 hours. Had the oil analyzed and had 'significant' fuel dilution. We surf 75% of the time. Kids tube the rest. I thought I could get a longer interval, but apparently not. Will change at 25 hours and analyze again. See if it makes a difference.
