I have a 94 Chaparral 2130 SS.

PROBLEM #1:
I have noticed in the last few times out that my oil pressure is high.
About 45 when idelling and about 60-70 when crusing at 80% of top speed. I
checked the oil and the oil pressure sender both seem to be fine. Any
suggestions? I don't know if this could be related but a friend of mine ran
into a sand bar about 1 month ago (no damage or anything tho).

PROBLEM#2:
Also I noticed the last few times out that when cruising at normal speed i
saw a blue type smoke, (nothing was overheating tho). I stopped the boat
but couldn't pinpoint anything (no leaks). Then when attempting to start it
it would stall out after idelling for about 20 seconds. I let it sit for
about 5-10 minutes then it seemed to run fine the rest of the day. Any
suggestions?

Could these two things be related?

Thanks for any input!
