cowl insulation

[my1stboat1]

I picked up a 1/2 inch insulation blanket and decided to cut and adhere it to the cowl on my 85 hp force outboard.. I let it sit a few days for the adhesive to harden... Started the engine and was completely impressed at how much quieter it was.. 1 concern though, Is the only air inlet for the engine just on the top of the cowl near the handle lift area...

Nope! Up to 1994, the main air inlet was under the carbs

Yep I thought about doing to but started to like the sound of my motor . One time I thought I had throwed a rod and after limping home and sick gut feeling was pleased to find one bolt out of crankshaft housing . Best thing I did was to find where air was comming into motor and take a unibit and drill open a couple notches . water pump is still orignal only replaced thermostat with washer restrictor and can troll for aqbout 20-30 min before alarm came on I stop and rev in neutral till it goes off and started again . Frank's right look below carbs there is two 1/2" holes to breath so drill away and I wanted to insulate but aways worried about heat . Old boat for sale comming to craigslist soon restorable , antique ,classic boat,4 new tires , can't sink or not get home . good luck on fuel/motor prob . did both carbs on new boat this weekend and the 4.5hp was harder then mercruiser .Still have old bass/walleye boat motor with beacon light to shine your way and it has chyrsler emblem on it and if you could guess the hp I might give it away with the new 4 tires .
