    low oil pressure alarm.

    Thanks for your replay. I wanted to add a flush that can be used from the deck so I don't have to get down to the engine compartment every time I flush.

    low oil pressure alarm.

    Thank you all for the replies. Sorry I went MIA but I was having problems figuring out how to reply to all of you and I am computer dumb. Also this boat was driving me nuts. She is a 1999 signature 260. I bough from and older gentleman who gave up on her after installing a new engine block (a mechanic told him he needed one) and couldn't figure out why the alarms and overheating also after reading all the paper work from multiple shops I concluded that he had too many different people working on her so I got stuck with a few issues. Here is a list of what it took to make her run right Serviced outdrive, replaced below and gimbal bearing. Fuel smell.....checked entire fuel system found small leak in gas tank ( cut floor, fire wall removed and install new one ) what a job. She wont go over 3000 RPM. checked fuel system again (found fuel pump looking tire) replaced fuel pump, cooler, etc. Still she wont go above 3000 RPM. checked Electrical system found wrong plugs. replaced all plugs, wires, distributor, rotor and cap. Now she moves. Now that she goes above 3000 oil pressure drops alarm goes on. (still haven taking her for a good run so no issues with overheating (yet) ). plugged diagnostic tool confirmed it was low oil pressure alar. mechanic changed oil and filter problem solved. Took her for another ride, temperature started to rise 180 - 195+. checked all houses, ricers, manifolds, oil cooler, replaced thermostat and raw water impeller. took for a ride and temp continue to rise again. Ordered Groco true hull, valve and 90 elbow. new raw water hose and installed and cut hose at the outdrive. (need to add a sea strainer). Took her for a ride and she runs great. I want to add a fresh water engine flush any recommendations??? once again thanks for all the advice.

    low oil pressure alarm.

    gauge reads 40 to 45 idle and in the no wake zone, 50 to 55 at 3000 rpm when reaching destination and slowing down gauge goes to 40 38 and alarm goes on. not sure of what type of oil did the previews owner used. we just changed it to 25 50 and replaced filter with a taller one (my mechanic recommend it ). going to try to test ride tonight.

  9. Can anyone help me with this? This is my first chaparral ( a 1999 260 sig) wich so far I love. It has a 350 mag MPI. she its giving me a low oil pressure alarm when I slowdown in the no wake zone. I have checked all gauges and fluids and they seem right. the last time it did it, the alarm went away after restarting and going about 3000 rpms for a few minutes. My question is... can the wrong oil cause that. I am having my mechanic change the oil and filter today. I appreciate any advice.
