OK so I'm pretty new to boating. I have a 1970 Mirrocraft Titan 15 foot with a Mercury 500 Thunderbolt 50HP.
I have an SE Sports whale-tail which gives me mixed results. If I don't run it, my prop vents a LOT and slips in the water. If I run it, it runs better but I think it slows the boat down...
I have a 1970 Merc 500 Thunderbolt 50HP motor. I bought the boat like two years ago and it's running strong but I've never done the water pump. The previous owner claimed it was done the years before he sold it to me and I've only taken it out like a dozen times so I'd not bothered yet and just...
I bought a 1970 Mirrocraft Titan 15 as a restore project a couple years ago.
Transom has been replaced. New deck, new seats etc.
When I had the old desk out I found the whole hull was pumped full of foam and it was all wet. Everyone suggested I pull and said it would make the boat faster...
I have a 1970 Mirrocraft Titan 15 with a 1970 Merc 500 50HP.
Sometimes I just loose power when going. This isn't an engine issue, engine runs great. Seems to be like, um, the best way to describe it would be to say I'm running out of water around the prop. The RPM's come up and its like I'm...
So I took my boat out for the first time this year 4th of July to watch fireworks from Gun Lake here in Michigan.
When I primed my engine I had raw fuel dumping out of the motor so I popped the covers and discovered that I was getting fuel spraying out of the fuel line that connects the two...
I have a 1970's Mirrocraft Titan 15. You can see the boat specs on the attached photo. Weight, length etc.
Boat has a 1970 Merc 500 Thunderbolt 50HP. How would I go about selecting the pitch that would be best suited for this boat?
When I bought the boat it has a Michigan Wheel 10 1/4 x 13...
I have a 1970's Merc 500. Engine is running pretty good right now but I'm about to rebuild the carbs and I've repaired some wires that look less then um, safe!
I have a question about the stator.
So if this part is working properly, should the battery loose power as the engine runs? Is there...
Bent the prop on my 1970 Merc 500. I believe the motor to be the original that came on my 1970 Mirrocraft Ski-N-Troll so I assume the prop is matched to the boat setup?
The prop is very worn too and I can barely make out the lettering but I believe it says:
10 1/4 x 1
Can someone tell me if...
Damn it all to heck! I bent the prop on my 1970 Merc 500! I was on a river trip and hit something. The water didn't seem too shallow but I think there was a rock or something hard sticking up and I heard it hit and whack several times. I took a small chunk out of the edge of one of the blades...
Just wanted a quick opinion.
I had a bit of weight in the back of my boat and yes I realize I can move my fuel tank and batteries to the front but my friends all swear by the SE 300 and SE 400 Sport Hydrofoils. I prefer the no drill option simply for not drilling but I have one mounted right...
Mind you that it's not MUCH water at all but I've noticed that when I come back in from the lake my lower unit gear case has milky white-ish colored gear fluid in it.
I always drain it right away and let it drip for a couple hours then fill it right back up til it over flows to push any water...
I have a 1970 Merc 500 I've recently had a lot of trouble with due to carbs, water, life etc. I got it running again and I'm thinking about adding a fuel / water separator to the fuel line.
I currently have an inline OEM Mercury fuel filter so I'm wondering does the fuel / water separator...
So I've been having various engine troubles the past couple days.I just realized I'm not actually getting fuel to the engine via the bulb now.
I can pump and pump the bulb and it never gets hard.
Brand new factory OEM Quicksilver/Merc bulb. Brand new lines. The only thing I reused were the...
First off excuse my grammar, I'm sending this from Google Chrome on my iPad on my lunch break!
I just picked up an old 1970 Merc 500 Thunderbolt with electronic ignition. It started right up when I got it, ran OK with only minor hesitation that passed as soon as you opened up the throttle. In...
Actually I just edited this thread. I have a timing belt question too.
How loose should the belt be? I can grab a hold of it and it's got a bit of back and forth flex. Are boat motors considered interference engines? What happens if the belt breaks? I will post a video of how much play it has...
