What is the fuel-oil ratio on a Sears 7 1/2 HP 2-cycle boat motor?

I thought it was 4 to 1, but better check your manual ,or the website, they would have more specific info.  Also, the fuel to oil ratio could be pretty generic for that type of engine, so even if you lost your maunual, find the stats for a similar engine and you should be safe.\n\nEdit: lol, better listen to the below poster, 4:1 and 50:1 is a pretty big difference, and I don't want you to send me your repair bill ; )

I believe that the following link is what you need.\n\nI hope that helps\n\nP.S they use to make bloody good lawnmower engines!\n\nAnhar Hussain Miah

~0.8 g/cc for cooking oil, and ~0.7 g/cc for baby oil.

Try Global Spec. It's free and allows you to put in your desired torque and rpm, then shows you matching products. Keep in mind they will spam the email account you register with mercilessly.

chilton repair manuals has a book on the motor which does have diagrams for the motor. beyond that the boat has very little wiring. lights, a pump, horn, and not much else came standard.

NOPE  1.5...WELL WHAT YEAR ENGINE AND WHAT CUBIC INCH??????

You need to mechanically generate motion to turn the shaft of the motor/generator at the speed specified on the name plate. Say 1800rpm for a induction motor would then generate the given voltage at 60Hz.\n\nIt is important to maintain this motion otherwise the frequency will vary.\nThe torque to maintain this motion is related to the load on the motor. So a 1 hp motor is about 746 watts. So for a 10kw turbin you will need a 2 x 15HP motor or 30HP motor due to a 50% efficiency factor for the maximum load. Most of the mechanical energy goes into heat.

In engineering practice we normally use kilowatt units for calculations. But horsepower is used for commercial terms and to categorize a motor. The conversion factor is 0.746 KW = 1 HP and 1KW  = 1.3405 HP

Most stock engines run 4 to 7 psi.

engine power is given by,\n             Power = (2*П*N*T)/60  , W\nwhere, \n                N = speed of the engine,rpm\n                 T = torque = F * r, N-m\n                 F=Force,N\n                 r = radius of the brake drum,N\n                 \n If you want power in horse power,\n                   H.p = power( in W)/746

Have them start it up , listen to the engine. Look under the motor housing to see how clean it is. Look for any build up of oil anywhere on the outside of case. The most important thing that will tell you if it was ran hard and beat up is the condition of the prop.If you are trying to figure out size then just look up what it the boat is rated for, and check out similar boats with smaller or bigger motors.

Mate this question is very open ended.\nBig fast powerful?\nSmall slow economical"\nPetrol?\nDiesel?\nSingle?\nTwin?\n\nI recently brought a 12m (38') Cougarcat from Bermagui (Southern NSW Coast) to Brisbane a distance of 600 NM. The vessel was powered by two TAMD63 6.3 Litre turbo Volvo Diesels. The vessel burned about 80 litres per hour. Used 2700 litres of fuel. At an average price of $1.65 per litre for diesel, it cost $4400 in fuel to do the trip.\n\nThis was a big relatively fast charter boat. Even at 29' There is a huge difference in fuel burn between a two cylinder diesel in a sail boat using 4 litres per hour and two petrol mercruisers using 120 litres per hour. So it is impossible to answer your question at all until you have some better data.\n\nOne thing to think about would be a Yacht. I must stress though, make sure you learn a lot about sailing both in a theoretical and practical sense before undertaking a journey of this magnitude. I have been driving rescue boats for almost 10 years, and I am still not ready to take on a journey like that one.

Horsepower = torque in lbf.ft x rpm / 5250.

I wish my husband were home to help you on this one, however I found the manual for his Minnkota Riptide Trolling motor the phone numbers are 1-800-227-6433 or 1-507-345-4623 (technical service departments). I hope this helps a little, they may be able to send you a manual via mail. GOOD LUCK!

A motor is electric and a motor runs on fuel, like gasoline or diesel.

your best bet is to get in touch with the guys who built the motor and know it the best. these guys will tell you the right answer and they wont just be guessing. D.S.S.  Phone: 630.587.1169 or e-mail ecom2000@dssracing.com and here is their website http://www.dssracing.com/

Probably inboard/outboard, referring to the type of motor.
