i havea 15 ft manatee with a <br />1978 chrysler 85 hp <br />mod# 859h8a<br />serial# 2552<br />engine starts idles and runs wide open in the water but has no power in mid range and also will die when put in forward . some times pushing the choke switch helps it. i just bought it after it sat for 2 years and used it over the fourth and then came home and started repairs listed below. should i check or replace anything else?<br />i have installed new carbs rebuilt fuel pump lookin for new cap and rotor and wires if any one has them.

Howdy IC...<br /><br />One thing that would cause your symptoms is late advance of ignition timing by the throttle linkage.<br /><br />You will need a manual if you don't have one. Check the throttle/carbs/ignition linkage and synchronization.<br /><br />Good luck. :)
