Has any one come across a downloadable excel spreadsheet for calc HP loss as engine room temp rises?. Found some webpages but I need to take a excel sheet with me. My boat is in the Caribbean were the avg ER temp is 85F when cool. However it was climbing to 120F when underway. I have since refitted a new ER ventilation system which changes the complete ER air every minute, with ducted air right to the engine intake areas. Sadly I have not been able to sea trial these improvements, only alongside trials
Provisional calcs revealed my 30yr old FL 120's were losing 11% to the hot 120F air aspiration. So take in transmission, age, and other loss's. I was losing some performance.
But I would like to accurately quantify these loss's when I go back to the boat after the hurricane season at the end of September. So if anyone has come across a spreadsheet I would appreciate the info
