I have a '88 150HP Mercury sitting on stand in the shed just waiting to be parted out. If the 200 uses the same parts as the 150 let me know. The only bad part is the crankshaft. The model and serial: 0A906046 7150726 Regards Carl

I think I may have found my issue with the water flow on this engine. I was running at 3K rpm and inspecting the engine for any source of water leakage where it shouldn't be. I found water spurting out at the exhaust plate connection - where the power head meets the exhaust tower. It looks...

I have a mercury 150hp o/b and I use the racor # 3227. I have the racor with the clear bowl that threads onto the filter so you can see and drain any water. Regards Carl

I used the Mercury OEM pump kit replacement included Impeller, gaskets, upper housing, small plastic water tube etc. For the pressure gage, does this get attached at the hole at the top of the engine that has a threaded plug in it? Thanks Carl

Ferm, I retorqued the bolts about a week after I reinstalled the head. I have not rechecked them after I ran it yesterday. I will do that soon. I looked at the water tube for as far as I could see it when I had the lower unit off. This is what I had done when the lower unit off, the t-stats...

Alright - fast forward almost a month from the last issue. I rebuilt the water pump, replaced t-stats, replaced all the parts of the popit valve and pulled the head just to be sure there was no blockage - (there was not). So I put everything back together and tested it in the yard. Everything...

I have one from a mid 80's 150 mariner model. The part # is either 5454A32 (1/2" thick) or 5454A35 (5/8" thick). I would need to measure it if you think it would work. Regards

Thanks for the info on the oil injection. I'll check the hoses too. Another question - If there is a blockage in the engine block, would I gain enough access by pulling the cylinder head, or would it require a more invasive disassebly? Thanks again

Thefermanator, I replaced the soft parts of the poppit valve and ran the engine without t-stats just to see if they were creating the problem. It seems to be happening regardless. Another crazy thought - could this be an oil issue? The previous merc I had did not have direct oil injection I...

What would cause only one side of an engine to run hot? I have mercury 150hp and the port side runs normal (this side has the temp sensor which sends the signal to the guage). The starboard side runs HOT !! This side houses the sending unit which activates the high temp alarm. I replaced the...

Thanks. That makes me feel better.

I am wondering what you folks recommend for a sealant in the bolt holes when mounting an engine? My previous engine had a clear silicon type product that seemed to be effective and was fairly easy to remove. I am in the process of buying a new to me (2005 Honda 150) engine and the installer is...

From what I could find, my old engine (150 hp mariner) I believe weighs around 375 pounds. Am I adding too much additional weight (over 100 pounds) to the boat? Can this be compensated with trim tabs? Thanks

I am in the market for a new to me motor and I have found a Honda 150 4-stroke with low hours for a decent price, but it has a 25" lower unit. I am wondering if anyone has used a jack plate to mount the motor higher on the transom and what the results have been. Is this a good idea? The motor...

So I convinced my wife to go take a look at the northcoast on Sunday. She really like the boat. I was happy to see her get excited about a new boat. :happy: Now I just have to swing some financing and work the deal. :sly: I am trying to set up a test run tomorrow. Carl

As I mentioned in another post, my motor failed in a big way a few months ago. I have ignored it as a coping tool the rest of the fall since I did not fish since the end of September. Anyway, the motor has run flawlessly all year and even the day it failed. After hours of fishing and...

I have a offer / opportunity that I can purchase a 2006 Northcoast 20 with a Suzuki 150 (2006) (4-stroke) for around 12K. My current situation is - I need a motor for my V20 since my 1986 Mariner broke in a big way this past fall. I have been shopping around for rebuilt and used motors and...

I tried parts.net and had ordered it through them. Everything stated they had one ready to ship. I waited five days and then received an email stating they did not have any in stock. (a bit frustrating) I did not try http://www.nickscreativemarine.com/f...ion_detail.asp, but I bookmarked...

When I removed the plug last weekend to check / add fluid to the T/T reservoir, the plug seemed really dried out and the slot and hex are now in such bad shape I need a new plug. This is a part that is no longer available from merc or many other places. I found a place online that had stated...

Has anyone heard of or ever used a product called thermagasket? http://www.rxauto.com/ It's made by Rx Auto It's proclaims to fix a failed head gasket. I have a '99 ford windstar with 128K miles with a bad head gasket. I tried the BARs product which did not work. The cost of the repair...
