Any Airflow Differences between 300xs and 250xs Cowlings
Hi, I have a Mercury 250xs Sport Cowling (Mercury part# 8M0024787) and a 300xs exhaust plate with offshore mid.
I am looking to install a dressed 300xs powerhead however am concerned whether my existing 250xs Sport cowling will flow enough air to feed the 300.
Can anyone confirm whether the internal air passages on the 300xs cowl are the same as the 250xs Sport cowl and the difference part numbers are just due to the different stickers on each cowl?
Thanks again-Rob
