So getting back to my thermostat situation....I tested my old one and it worked but it opened at 165 F......It was recommended I buy a 140 F thermostat for my motor....that being said if I use the new 140 F, will my motor run right at low speeds and idle or will I need to goof around with the...
Yes Lou....
It's a workhorse.....I bought the boat and trailer 15 years ago for $600 just for the trailer and I was going to use the trailer for a different boat but kids and life forced me to keep the boat anyway, redo the seats and all of the vinyl and she still gets us around.... the motor...
Awesome and thanks!!
I took the thermostat out of the housing and it already was open 25%...it's pretty old so I think I'll clean it up, order a new one, reinstall the old one and see if it keep acting up....if not, I'll switch it out when I winterize the old girl...
I'll go with the 140 F...
Thanks for the response....I can remove it and test it.... I believe thermostats are closed when cold and open at a certain temp....probably best just to replace it and hopefully eliminate the problem.....I think there were 2 different thermometers with different opening temperatures listed for...
Good Morning and it's been a long time since my last post...
I have a very old girl, 1976 Starcraft American 20......She has a straight six, 165 HP Merc sterndrive..., This spring I changed the impeller in the lower unit because it had not been changed in 4-5 years. I have a fuel pump and...
Hello,
I have what I believe is a dead coil in my '74 StarCraft American 20 that has an almost vintage 165 Mercrusier straight six motor with a MC-1 outdrive. The boat had run fine all season so far and today it began stuttering while I was slowly cruising in the NYS Barge Canal. I got her...
Hello,
I need to change the drive shaft oil seal on my 1976 Mercruiser 140 MC-1 outdrive. I was wondering how difficult it will be to remove the bearing retainer from the upper drive. I will be receiving the retainer wrench shortly but I am a little concerned with removing the retainer...
Hello,
I have a project Mirrocraft 21' with a 1974 Mercruiser 140 HP with an MC-1 outdrive. I pulled the outdrive for the season and discovered a mess of outdrive oil and water in the bellows. This has never happened to me before and I was quite shocked to see this mess.
Can someone help me...
Hello All,
I have an old 21' Mirrocraft 1976 that has a Mercruiser 140 and an MC-1 outdrive. I am starting to refurbish the boat but I have a trim motor that does not operate when I want it to go down. It works fine going up and now it is stuck in the up position.
The trim motor has only...
Hello,
I have a 1978 StarCraft American 20 that has a 165 HP Mercruiser motor and a MC-1 outdrive. It weighs 1700 lbs. The prop on it now is an aluminum 15 1/2 x 17 that has a bunch of nicks and gouges on it from old age. I wanted to replace the prop with a stainless steel model and I was...
Hello,
I need to replace the spark plug wires and rotor cap on my 1978 StarCraft American 20 that has a Mercruisrer 165 and an MC-1 OD and I was thinking of upgrading to an electronic ignition system. I have heard great feedback regarding E/I but I am a little reluctant to spend the money and...
Hello,
I bit off more than I can chew with my latest rebuild project. I took on a 1976 21' aluminum Mirrocraft with a fair 140 Mercruiser and a MC-1 O/D. I gutted the boat and planned on redoing the whole works but the scope of the job and the fact my wife would rather have a large bowrider...
Hello,
After using my 1976 Starcraft 20' American (165 HP & MC-1 O/D) all over Keuya Lake for vacation I noticed my outdrive was failing to go up all the way if I was in shallow water. Going down was fine but going up, I needed to hit the down button and up button rapidly until I could hear the...
Hello,
I have been trying to get an old tin can ready for restoration or to sell outright. The boat is a 1972 Mirrocraft 21' with a 140 merc and a MC-1 outdrive. I got the motor running well this am, it started easily, and after I adjusted the 2 carb jet screws it was running like a top.
I...
