Oil pressure switch?

[Bill425]

I got a 2016 243 chaparral with twin 250 hp supercharged brp rotax engines. Model of engines are 1503. I posted previously regarding an engine oil leak but managed to locate it and it ended up being the very center of the oil pressure switch. My problem now is locating the correct replacement along with the part number and an on line parts supplier. I talked to 2 dealers so far and both weren’t to knowledgeable regarding the part. Can anyone provide some information on the part or can an after market part be substituted? Hope someone can help! Thanks!

2 weeks ago I ordered the pressure switch and am waiting for it to come in. Looks like I may be able to remove the old one with a deep dish socket without removing the throttle body by going straight in under it using extensions. Did you replace yours yourself? If so, how did you do it?

i have changed this only with a 24mm nut (long version) in under 10 minutes. i dont remove other parts by this job. very easy

I have been waiting for the oil pressure switch which I ordered from the dealership back on July 19th and it still hasn’t come in. Do you know what the part number is that you used and can you use a compatible part from seafood?

 

[Mr.Happy]

Only the number what you see above.... i have no another number.

Put the new switch in and reset computer on medallion screen but P0024 still comes up as oil pressure switch and can’t be cleared. Engine still runs in limp mode. Have a seafood tech coming with buds diagnostic to see what the problem is. Will keep you posted.
