Spread the cost of marine inboard diesel engines from £8,000 to £90,000+ with flexible finance options. HP, lease, or refinance
Yes, inboard engines are financed as a standard asset purchase, usually on hire purchase or a lease, with the machine itself acting as the security. UK prices typically run £8,000 to £90,000, and most deals are written over 24–72 months with a deposit of around 10–20%. Decisions typically take 24–48 hours. Used machines are financeable too, usually with a shorter term.

Guide prices for sizing a finance agreement, not quotes. Manufacturers in this market mostly price on application, so where a current UK list price could not be confirmed the row describes a specification class rather than naming a model. Your supplier quote is what the agreement is written against.

Marine inboard engines used for business qualify for Annual Investment Allowance (AIA), letting you deduct the full cost from taxable profits in the year of purchase, up to £1,000,000. HP agreements let you claim capital allowances on the engine; lease payments are generally deductible in full against profits.
Inboard diesel engines are bought by fishing vessel and workboat owners, ferry and charter operators and marine engineering yards, most often as a repower of an existing coded hull rather than a new-build purchase, since a full re-engine can cost a fraction of a replacement vessel. Because the engine is going into a vessel that already holds MCA coding, lenders typically underwrite the application against the vessel and operator rather than treating the engine as a fresh coding question, though a significant power change can trigger a recoding review with the certifying authority. Inboard installations are more involved and time-consuming to remove than an outboard, which gives lenders a little more comfort over recovery risk, though the vessel itself remains a mobile asset. Engine hours, oil analysis and service records matter far more to used value than the calendar age of the block.
Some specialist lenders consider businesses with imperfect credit histories. You may need a larger deposit or personal guarantee, but options may be available. Fundably may use a soft credit check for matching, which does not affect your credit score. A hard check may happen if you choose to proceed with a lender.
