mercury poppet

[Blue197320]

hey everyone. i splashed my boat after the console rebuild and motor change. now its overheating. it only does it when its under load. the engine is an 84 2.4 but its bolted to a 97 (i think) midsection with the 2.5 exhaust hole plugged and the oval exhaust ports cut out. i posted my problem on S&F but no replies yet. im hoping some one here can tell me if i need to change the poppet valve. because the t-stats are new (it didnt have any before) and the water pump was put in in november last year and it hasnt been run till now. thanks for your help
